Peter Mullan was injured trying to stop an assault outside a Glasgow venue. What the verdict reveals about venue perimeter safety and bystander protection.

Peter Mullan assaulted while intervening — why this verdict matters for venue safety

Hook: If you’ve ever hesitated to step in when someone is in danger at a gig or public event, the recent Glasgow court verdict involving actor Peter Mullan exposes exactly why venue safety and bystander protection must change — fast. The case is a wake-up call about perimeter security, steward training and the legal protections (and risks) for people who intervene.

Topline: what happened and the legal outcome

In a high-profile ruling in early 2026, Dylan Bennet was jailed for 18 months after a court found he assaulted actor Peter Mullan and an unnamed woman outside the O2 Academy in Glasgow. According to reporting from BBC News and coverage by Deadline, Mullan intervened after seeing a woman distressed outside the venue in September 2025. Bennet responded by headbutting Mullan — inflicting a head wound — and reportedly brandishing a glass bottle at both victims. The court heard Bennet had been drinking and using drugs throughout the night; his lawyer said he deeply regretted the incident.

“Mullan tried to come to a woman’s aid after he saw her crying outside of the O2 Academy venue in Glasgow… He attempted to intervene before being headbutted by Bennet,” — BBC News (paraphrased).

Why this case matters beyond celebrity headlines

At first glance the story registers as a disturbing celebrity assault: a recognizable actor injured while trying to help someone. But the verdict and surrounding facts illuminate structural problems at live events and public spaces. This is about:

Perimeter safety — what happens outside ticketed areas where most venues have fewer controls.
Alcohol, glassware and weaponized objects — common risk multipliers at gigs and clubs.
Steward and staff capability — whether on-site teams can intervene quickly and safely.
Bystander risk and the law — whether those who step in are protected or left vulnerable.
Technology and data — how CCTV, AI analytics and rapid comms can detect and stop incidents before they escalate.

The legal signal: courts protect interveners

The 18-month sentence sends a clear message: courts are willing to impose custodial sentences where violent, alcohol-fuelled assaults target people trying to help others. For public safety advocates and venues, the ruling strengthens calls for proactive measures that reduce the burden on bystanders and improve official responses.

Breaking down the incident: a short timeline

September 2025 — a woman is upset outside the O2 Academy in Glasgow after a concert.
Peter Mullan approaches to check on and intervene on the woman’s behalf.
Dylan Bennet reportedly headbutts Mullan and brandishes a glass bottle; Mullan sustains a head wound.
Bennet is arrested, charged, and in early 2026 is jailed for 18 months after conviction.

Four immediate safety takeaways for venues and promoters

This case exposes gaps that can be fixed with policy changes and technology deployment. Practical, evidence-based steps that venues should implement now:

1. Extend the security perimeter

Too many incidents occur outside ticketed areas where staffing drops off. Extend coverage beyond doors and fencing to include pavements, entry lines and taxi ranks. Specifically:

Deploy visible steward teams outside for the full ingress/egress window.
Use rovers (mobile teams) to monitor crowd flows and intervene early.
Coordinate with local police and private security to time patrols for peak exit times.

2. Remove or mitigate glass and weapon risks

Glass bottles are repeatedly linked to serious assaults. Countermeasures that we’re seeing in 2025–26 pilots include:

Switching to polycarbonate or aluminum drinkware for outdoor and high-capacity shows.
Strictly enforcing no-glass policies with clear bag searches and amnesty bins at entry.
On-the-ground campaigns reminding patrons of the risks of weaponising drinkware.

3. Train and equip stewards for rapid, safe intervention

Steward training must go beyond crowd control to include conflict de-escalation, basic first aid and safe restraint techniques. Best practices for 2026:

Quarterly, scenario-based training drills involving police and medical teams.
Wearable comms (push-to-talk devices) linked to venue control and local emergency services — integrate these into your broader edge and operations plan (see stadium & edge ops guidance).
Panic buttons and silent alerts that flag incidents to command centers instantly.

4. Upgrade detection with privacy-first tech

Since late 2024, venues have been piloting AI-driven CCTV analytics and sound-detection systems that flag shouts, fights and suspicious movement in real time. Implementation tips:

Opt for systems that run rule-based alerts (e.g., clustering of violent gestures) rather than intrusive face-identification where privacy guidance prohibits it.
Integrate camera alerts into steward dashboards to reduce response times.
Keep transparent data-handling policies and signage so patrons know when monitoring is active.

Bystanders: how to help safely — practical guidance

Many people hesitate to intervene because they fear legal fallout or personal injury. The Mullan case shows intervention can be heroic — and risky. Follow this step-by-step approach if you witness an assault:

Assess — Is the threat escalating? Can the victim be moved to safety without you entering harm’s way?
Alert — Call venue security immediately and call emergency services if there is significant violence.
Record — Video from a safe distance can deter attackers and provide evidence, but avoid getting between combatants.
Support — After the immediate danger, check for injuries and stay with the victim until help arrives.
Report — Provide witness details to police and secure any footage you captured.

In the UK, reasonable force to defend another person can be lawful, but that does not mean stepping into a brawl is wise. If you’re untrained, your intervention can make a situation worse. Prioritise calling professionals while using non-confrontational methods whenever possible.

Legal context and implications — what the verdict signals

The sentence handed to Bennet illustrates two interlocking legal principles relevant for venues and interveners:

Criminal accountability: Violent, alcohol-fuelled assaults are being prosecuted aggressively, especially where a weapon (a bottle) is used or where an innocent third party is targeted.
Recognition of interveners: Courts are likely to view people who step in to protect others as victims deserving of protection rather than perpetrators.

For venue operators and promoters, the ruling creates a stronger argument that insufficient security measures could expose them to civil liability when foreseeable risks (e.g., fights near exits) are not mitigated.

On bystander protection law

Countries vary on whether “Good Samaritan” protections exist. The UK does not have a single national statute protecting bystanders who intervene, but case law often recognises the right to use reasonable force in defence of others. What’s changing in 2026:

More calls from safety groups and some local authorities for clear legal guidance and training funding for citizens and stewards.
Industry standards being updated to make steward training and perimeter coverage mandatory in best-practice contracts for large events.

Technology & policy trends shaping venue safety in 2026

Three trends accelerated in late 2024–2025 and matured into mainstream practice by 2026. Organisers and venue managers should be tracking these.

1. AI-assisted incident detection

Real-time analytics that flag patterns of aggression, crowding and glass use can cut response times dramatically. Ethical deployment — with clear governance and data minimisation — is essential to avoid privacy backlash.

2. Decentralised emergency comms

Mesh networks, venue-wide push-to-talk and smartphone-linked panic alerts give stewards and staff redundant channels if cellular networks get congested at major events. Operators should consider the same edge and ops frameworks used in stadium-grade events (stadium & edge ops).

3. Integrated medical + security coordination

Joint training and shared incident management platforms between security and medical teams reduce handoff delays and improve survivor outcomes when assaults occur.

Practical checklist: Immediate actions for venues (implement this week)

Run a perimeter safety audit: map blind spots outside entry/exit areas and assign patrols.
Review glass policies and consider temporary switch to non-glass drinkware for upcoming shows (vendor tech review).
Mandate scenario-based steward training before high-capacity events and mandate quarterly refreshers.
Install or upgrade real-time alerting tools (wearables, panic buttons, camera analytics) and test end-to-end.
Update patron messaging — clear signs about how to report incidents and where to find help upon exit. Consider portable event logistics and fulfillment options for temporary staff and vendor needs (portable checkout & fulfillment).

What fans and celebrities can do now

For concertgoers, activists and public figures who still want to help others in public spaces, the Mullan case is both inspiring and instructive. Steps to reduce personal risk:

Avoid intervening physically unless you’re trained; prioritize calling security.
Record evidence safely from a distance; timestamp and save multiple copies to avoid accidental deletion.
Get witness contact details and a short written statement while details are fresh.
If you are a public figure, plan exits and carry minimal valuables; but don’t let the risk of attack deter you from supporting victims in non-confrontational ways.

Longer-term policy shifts to expect in 2026

Based on industry momentum and the public conversation sparked by cases like Mullan’s, expect the following developments this year:

Formalised venue safety standards tied to licensing for mid- and large-capacity events.
Expanded public funding or tax incentives for venues to adopt safer infrastructure (lighting, CCTV, staff training).
National guidance on steward-to-patron ratios and perimeter coverage for concert halls and stadiums.
Campaigns to reduce glass and single-use glassware at events, driven by insurers and venue owners.

Risks and trade-offs: privacy, costs and crowd experience

Improving safety is not cost-free. New measures must balance safety with patron privacy and the live-event experience:

Privacy: AI and camera analytics must be deployed with transparent policies to avoid public pushback — use privacy checklists like protecting client privacy when using AI tools as a starting point.
Cost: Smaller venues may struggle to fund advanced tech and additional staff; subsidies and scaled solutions are needed.
Atmosphere: Over-policing can chill the fan experience. Training on proportionality is essential.

Final analysis: the Mullan verdict should be a turning point

The assault on Peter Mullan and the subsequent sentence for Dylan Bennet are more than tabloid fodder. They crystallise persistent vulnerabilities at the margins of live events — outside venues where catastrophic incidents too often begin. The legal outcome affirms that the courts will treat attacks on interveners harshly, but criminal justice alone is not prevention.

Prevention requires a coordinated approach: better perimeter security, smarter use of technology, robust steward training, clear policies on glass and alcohol, and legal clarity for bystanders. Those steps will protect patrons, performers, and the people — like Mullan — who step in to help.

Actionable takeaways

Venues: start a perimeter safety review this week and pilot non-glass drinkware.
Promoters: mandate steward scenario training and run joint drills with local police.
Patrons: prioritise calling security, document incidents safely and volunteer witness statements.
Policymakers: fund training and pilot tech for smaller venues to level the safety baseline nationwide.
