Over 400 arrests were made during the 2025 Notting Hill Carnival, with police employing advanced Live Facial Recognition technology and other proactive measures such as knife arches and stop-and-search powers to monitor and prevent serious violence.

The arrests were distributed over the event days, with approximately 200 on the first day—including 149 at the event and 51 approaching—and around 223 on the second day, with 177 at the Carnival and 46 approaching.

By 7:45 pm on August 24, 2025, police reported a total of 140 arrests, including 105 at the event and 35 on the approaches, reflecting ongoing efforts to maintain safety.

Despite the overall success in policing, one police officer was injured and required hospital treatment, with authorities pledging support for affected officers.

During the festivities, two festival-goers were stabbed in separate incidents but sustained non-life-threatening injuries.

The most common crimes involved possession of cannabis (70 cases), Class A drugs (32 cases), and offensive weapons (46 cases), highlighting the focus on drug and weapon-related offenses.

Community leaders emphasized the event's role in promoting cultural unity and highlighted ongoing efforts to enhance safety through policing and community cooperation.

Additional police powers under the Criminal Justice and Public Order Act 1994, including searches without suspicion, face covering removal, and dispersal orders, were authorized from August 24 morning to early August 26 to prevent disorder.

Law enforcement utilized live facial recognition, knife arches, and stop-and-search tactics to target suspects and prevent serious violence during the Carnival.

These enhanced powers were in effect from 10 am on August 24 through 2 am on August 25, and again from 10 am on August 25 through 2 am on August 26.

Overall, police made 423 arrests over the weekend, with a notable decrease in serious violence compared to previous years, attributed to proactive policing strategies.

The Carnival celebrated Caribbean, African, and Brazilian cultures, featuring costumes, music, and floats, and is considered one of the largest street parties in Europe.
