Police have released new images of a man they urgently need to speak to in connection with the murder of a teenager in north London last week.
Detectives want to speak to 22-year-old Abdel Derdour about the fatal stabbing of 15-year-old Adam Henry in Islington.
Officers were called to reports of a stabbing on Westbourne Road, Islington, at around 1pm on 9 December.
The teenager's wounds were treated but he later died in hospital despite the best efforts of medical teams, the Metropolitan Police said.
Tsidi Winion, 20, of Handyside Street in Camden, was charged with murder and possession of an offensive weapon on Monday, according to the force.
Police are now appealing for the public's help to trace Abdel Derdour, who made off in the direction of Caledonian Road following the incident.
He is described as being approximately 5ft 8ins in height, of mixed heritage, with a slim build. He was most recently seen with a moustache and facial hair.

"If you have seen this man in the days following Adam's murder, please come forward. Even the smallest detail could be the breakthrough our detectives urgently need.
"Our intelligence suggests he frequents Holborn and the surrounding areas."

In a previous statement, Adam's family described him as a "loving son, brother, nephew, grandson, friend" and said they will "never recover from the loss and not having him in our lives".
"He had many interests and was always there with a smile and cheeky sense of humour," they said. "He was good-natured and loyal."
