A 16-year-old boy has been arrested on suspicion of murder and violent disorder in connection with a fatal stabbing in north London.

On Wednesday a 20-year-old man was found with stab wounds after police were called to reports of a fight between men armed with baseball bats at about 6.30pm on Cavendish Road, Edmonton. The man was later pronounced dead at the scene.

Police said the teenager arrested in connection with the case was receiving treatment in hospital and would be questioned later.

Extra police patrols will be deployed in the area where the incident happened. The killing takes the total number of murder investigations in the capital to at least 81 for 2018.

On Wednesday at a London knife crime summit organised by the mayor, Sadiq Khan, one of the UK’s most senior police officers said violence in the capital was on the rise.

The Metropolitan police assistant commissioner Martin Hewitt said: “If I was stood here five years ago, I would probably be talking about knife offences where there was generally a single puncture wound. We are now routinely seeing multiple stabbings. That is one individual stabbing somebody multiple times.

“Some of the CCTV footage that we see is shocking and quite frankly feral when you look at a group of individuals bearing down on another person.”

On the Edmonton incident, a Met spokesman said: “At this early stage officers retain an open mind as to motive.”
