Police have arrested a fifth teenage boy on suspicion of murder after a 52-year-old man was stabbed to death following a row.
Four boys were arrested on suspicion of murder after a 52-year-old man was stabbed to death following a "verbal altercation" with a group of youngsters yesterday evening, Scotland Yard said.
Police were called to a residential address in The Broadway, Edmonton, north London, at around 7.50pm last night following reports of a stabbing.
Scotland Yard said they believed the victim had been involved in a verbal altercation with a group of boys, aged in their mid-teens, as he attempted to gain entry into the block of flats.
Officers today arrested another 13-year-old boy in Enfield, north London, and he remains in custody at an east London police station.
The man was followed by two of the males and stabbed, police said.
The suspects, all believed to be aged 13 and 14, remain in custody at a north London police station.
Scotland Yard said the group of males were trying to get into a "supervised party" at another address within the block of flats.
They did not know the victim, who was with a woman at the time of the altercation, the force added.
Ambulance crews attended but he was pronounced dead at the scene shortly before 8.40pm.
A Metropolitan Police spokesman said the force believe they know the identity of the dead man but he has yet to be formally identified.
Detective Chief Inspector Neale Baldock, of the Homicide and Major Crime Command, said: "Our initial inquiries have established that there was a supervised party taking place at another address within the block and the group of males were trying to gain access to this.
"The victim and this group were not known to each other. What started as a minor verbal altercation has escalated into a shocking act of violence."
