On Sunday, Arsenal hosted Chelsea at the Emirates Stadium in a Premier League London derby marked by heightened security and extensive police coordination. The Metropolitan Police’s public order command led the operation, with Chief Inspector Pete Dearden serving as matchday commander. Dearden outlined a focus on safety, security, and service ahead of the 4:30 p.m. kickoff, describing the fixture’s risk level as “medium medium” based on factors such as supporter behavior, location, and match timing.

The Metropolitan Police deploys 17 dedicated football officers (DFOs) to work full-time with individual clubs, coordinating with matchday commanders to plan every fixture. For this game, three police support units (PSUs)—each comprising approximately 25 officers including inspectors and sergeants—were assigned, augmented by 20 operational “spotters” who gather intelligence and monitor fan behavior before and during the event.

Arsenal independently manages its own safety operation, mobilizing roughly 1,000 stewards and response team members trained to be first responders to incidents inside the stadium. Police typically intervene only when requested or when more serious situations arise; Arsenal requested a PSU presence within the stadium for the Chelsea visit under a special police services (SPS) agreement, part of a broader arrangement by which clubs may request and partially fund police support for matches. Dearden estimates police costs for football policing at about £23 million annually, with clubs reimbursing around 10%.

To mitigate risks and reduce the need for heavy police deployment, the Met is working with clubs to implement preventative measures such as managing road closures and hostile vehicle mitigation financed by the clubs themselves. The use of spotters—a locally based group familiar with supporter groups—helps monitor fan movements, moods, and intentions across key gathering points, including pubs and public transit routes to the stadium. Dearden emphasized that spotters’ ability to engage with supporters can help identify potential troublemakers, and a lack of engagement may signal planned disorder.

In an incident just before kickoff, a spotter performed life-saving CPR on a supporter, underscoring the wider remit of the security personnel deployed.

Outside the stadium, the Met ran a two-hour facial recognition pilot funded through a Premier League investment. This voluntary program used cameras to scan passersby, matching faces against watchlists of individuals subject to football banning orders or wanted for serious crimes. Six interventions resulted from the trial, including one involving a person recently released from prison on a human trafficking conviction. The pilot supported targeted enforcement against offenders who might threaten the safety of fans and others at match venues.

Police visibility for the match was deliberately moderate, aiming to provide a sense of security without intimidation. Dearden noted that the policing approach focuses on addressing “known knowns” rather than deploying large forces out of caution, with officers trained to de-escalate situations quickly and calmly to prevent flashpoints from escalating.

Following the match, which ended without major disruption, a debrief recorded a dozen incidents including two arrests—one for assaulting a steward and another for racial abuse and assault. Ten further reports covered offenses such as pitch-side drinking, missile throwing, low-level assault on stewards, homophobic chanting, and drug possession. Dearden acknowledged the incident count was higher than desired but framed it as evidence of effective and proactive policing, emphasizing consistent and proportionate responses.

Data from the day will be carefully analyzed to inform future policing strategies and improve matchday safety. For players, supporters, and security staff alike, the day ended with a sense of accomplishment in managing the complex logistics and challenges of policing a high-profile football derby.
