The man stabbed in what police believe was a follow-up to an argument in London has been named.

The victim, David Martinez, 26, was found in the street with multiple knife wounds on Wednesday afternoon in Leyton.

Mr Martinez was a Spanish national and although formal identification has not yet taken place, detectives are confident he is the victim.

Metropolitan Police officers, London Ambulance Service and London Air Ambulance were called to North Birkbeck Road in Leyton on Wednesday at 4.26pm to reports of a stabbing.

Officers have said the killing followed a clash that started in a nearby residential address.

It is thought that the victim and the perpetrator knew each other and that the killing was not gang related.

After Mr Martinez was stabbed six times - at least once in the neck - he collapsed in the arms of strangers on North Birkbeck Road.

The horrific incident was witnessed by children as young as two as passers-by and paramedics battled for 45 minutes to save his life.

According to The Sun an officer begged the man to stay awake as he lay dying, pleading: "My friend. Mate, mate, mate, talk to me. Can you hear me?"

Mr Martinez was found suffering from knife injuries and died at the scene at 5.10pm.

The next of kin have now been informed.

A post-mortem examination will take place in due course.

A crime scene remains in place at the scene and the Homicide and Major Crime Command are continuing investigations.

Anyone with information should call police via 101 quoting CAD 5145/6 March or Crimestoppers anonymously via 0800 555 111.
