Harlesden murder: Man dies after high street stabbing
A 21-year-old man was fatally stabbed on a London high street after a gang used two cars to block traffic.
Drivers were disrupted on Harlesden High Street at about 21:00 BST on Tuesday, when murder detectives believe the victim was wounded.
He staggered into a betting shop to appeal for help, but died in hospital at about 02:50 BST.
Seven men were arrested nearby and are being questioned by police, who are treating the man's death as murder.
The Metropolitan Police said they were being held on suspicion of offences including possession of an offensive weapon and attempted murder.
The victim's next-of-kin have been informed. A post-mortem examination is due to be held later.
Some 25 people have been stabbed to death in London so far this year.
