Four teenagers arrested on suspicion of murdering a man in north London have been released on bail.
The boys were held after a man was found stabbed at his home on The Broadway in Edmonton.
The boys, aged 13 and 14, are alleged to have stabbed the 52-year-old man. A fifth boy, 13, remains in custody.
Scotland Yard said detectives thought the boys and the man had been in a verbal altercation as he tried to enter the apartment block.
Detective Chief Inspector Neale Baldock said: “Our initial enquiries have established 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.”
