As the Emirates Stadium prepares for the highly anticipated Arsenal vs Chelsea match, Chief Inspector Pete Dearden leads an extensive police briefing focused on ensuring safety and security during this significant London derby. The 4.30pm kick-off carries weight, with the Premier League champions facing a formidable challenger.

Dearden, the matchday commander from the Metropolitan Police’s public order command, emphasizes the mantra of "safety, security, and service." With 60,000 fans expected, the police aim to minimize disorder risks. The Met deploys three police support units (PSUs) alongside 17 dedicated football officers (DFOs) who meticulously plan each fixture.

Key elements of the operation include:

• Collaboration with Arsenal's in-house safety teams: Approximately 1,000 stewards are prepared to respond to incidents.
• Risk grading of all 500+ games the Met covers annually, assessing supporter behavior and historical context.
• Spotters working under DFOs to monitor fan interactions and prevent potential disturbances.

Innovative measures, such as live facial recognition technology, enhance security by targeting individuals with football banning orders (FBOs) or serious criminal backgrounds. This pilot, funded by the Premier League, aims to deter high-harm offenders.

Before the match, a spotter performs life-saving CPR on a supporter, underscoring the importance of vigilance.

Despite a noticeable reduction in police presence, the approach is deliberate. Dearden states that a heavy police presence does not necessarily equate to safety. Instead, they focus on proactive engagement with fans to foster a safer atmosphere.

By match’s end, incidents arise, including two arrests for assault and racial abuse. Dearden reflects on the day’s outcomes, noting the need for ongoing analysis and improvement, but also acknowledges a successful matchday operation, ensuring a safer environment for all attendees.
