A 25-year-old man who died after running from police and entering a canal near Notting Hill Carnival has been named as Karnell Kelly.

The Independent Office for Police Conduct (IOPC) has launched a formal investigation into the incident, which occurred near Meanwhile Gardens, off Kensal Road in west London.

According to the watchdog, the encounter began at around 3.20pm when Metropolitan Police officers briefly spoke to Mr Kelly, who was wearing a face covering as he approached the carnival. Mr Kelly ran off immediately after the interaction, prompting officers to pursue him down Hormead Road.

The IOPC established that Mr Kelly subsequently entered the canal. Met officers and members of the public went into the water to pull him out, and officers administered emergency first aid before he was taken to hospital, where he later died.

On Wednesday, 2 September, specialist divers from the Met's Marine Policing Unit searched the area of the canal after it was confirmed that both Mr Kelly and a police officer sustained injuries while in the water.

Amanda Rowe, the IOPC's Director of Engagement, said: "Our thoughts are with the family and loved ones of Karnell Kelly and everyone affected by his death. We need to independently establish the exact circumstances of this incident given that he has died following an interaction with police officers. We are therefore appealing for anyone who may have witnessed and/or videoed any part of the incident to make contact with our investigators."

Detectives from the watchdog are currently reviewing footage from officers' body-worn video cameras. The Coroner's Service has also been informed, though an inquest opening date has not yet been announced.

The incident took place during the carnival's 60th anniversary weekend, which saw hundreds of thousands of people attend. Across the wider event, the Metropolitan Police recorded a total of 636 arrests—242 on Sunday and 394 on Monday—and reported two knife assaults, neither of which resulted in life-threatening injuries. Police described the overall atmosphere as positive and celebratory.

I'll be following the findings of the IOPC investigation as they develop and will provide updates when more details are established.
