An investigation has been launched after a man was stabbed to death.

Police were called to reports of a 23-year-old with stab wounds in Russell Road, near Seven Sisters station, just before 8.15pm last night.

The London Ambulance Service also attended, treating the man, before taking him to hospital.

However, the man died in hospital.

His next of kin have been informed and are being supported by specially trained officers.

A post-mortem examination and formal identification will be arranged in due course, the Met Police say.

Four men, all aged in their 20s, have been arrested today in connection with the stabbing, as police carry out enquiries.

They are all currently in police custody.

DCI Simon Stancombe from the homicide and major crime command said: "My thoughts are first and foremost with this young man’s friends and family at this tragic time. I want to reassure them and the wider community that we are doing our utmost to understand what happened yesterday evening.

"Our investigation is in its very early stages and while we have four people in custody in connection with our enquiries, I am still appealing to the public to get in touch with anything they may have witnessed that evening.

"Specifically I am keen to identify where the attack took place, and the sequence of events that led to this young man’s death. Anything you may have seen could be vital to our investigation so please do get in touch."
