Three teenagers have been convicted of murdering a young man in Harlesden who they chased and stabbed without any apparent provocation.
At the Old Bailey on Monday following a trial, Idris Daud, Ayman Koshin, and T-Shai Ennis were found guilty of the murder of David Headlam.
Daud, 19, of Anton Place, Wembley, Koshin, 18, of Summers Close, Wembley, and Ennis, 19 of Chadwick Road, Langley, fatally stabbed the 19-year-old - the son of a church minister Alonzo Headlam - in what police called an "unprovoked attack".
The trio were also convicted of grievous bodily harm with intent for attacking a 19-year-old man with David on the night in question - June 29 last year.
Jurors heard at around 1am David, of Donnington Road, Willesden, and his friend were first assaulted from behind in the High Street into Park Parade, and then pursued by the attackers onto Drayton Road where residents witnessed the further assault.
A people carrier vehicle picked up the two men, which police later discovered was a min-cab based in Wembley ordered from Koshin's mobile.
A post-mortem examination into the death of David - two hours later in St. Mary's Hospital - gave the cause as stab wounds to the thigh, cutting his femoral artery.
On the day of the murder, Daud uploaded a rap video on YouTube featuring Ennis and himself.
Part of the video showed Ennis bragging about stabbing someone, the jury heard.
Detective Inspector Sarah McConnell said: "This was an unprovoked attack against two friends who were making their way home after meeting friends.
"The defendants launched a violent assault, chasing David for some distance before delivering the fatal injuries.”
"Residents came to David's aid and remained with him until he was attended to by emergency services.
"I would like to thank those who assisted, and the witnesses who subsequently came forward to help the police investigation.
"Our thoughts are with David's family and I only hope that the convictions of those responsible will offer some small comfort to them at this extremely difficult time."
The trio will receive sentencing at a later date to be confirmed.
