Man arrested on suspicion of murder after fatal stabbing of 15-year-old in London

A 22-year-old man has been arrested on suspicion of murder after a teenager was stabbed to death in north London.

Metropolitan Police officers arrested Abdel Dedour on Boxing Day after a two-week manhunt following the murder of 15-year-old Adam Henry.

The teenager was fatally stabbed in Islington around 1pm on 9 December, the force said.

Officers and paramedics from the London Ambulance Service attended and Adam was taken to hospital, where he died.

The force said it made five arrests at an address in northwest London on Boxing Day.

As well as Dedour, three men and a woman, aged between 18 and 47, were detained for assisting an offender.

The woman, aged 47, was further arrested after an assault on a police officer while one of the three men, aged 39, was further arrested for domestic violence and driving offences.

All five remain in custody.

Adam's family are being supported by specialist officers, the Met said.

"Our thoughts remain with Adam's loved ones throughout this unimaginably difficult time," said Detective Chief Inspector Allam Bhangoo, who is leading the investigation.

"There is no place for senseless acts of violence on our streets - and those responsible for such crimes should be brought to justice.

"My dedicated team have worked tirelessly over the last few weeks."

Tsidi Winion, 20, of Handyside Street, in Camden, was charged with murder and possession of an offensive weapon on 15 December and faces trial next year.

Adam's family described the teenager as "good-natured and loyal".

In a statement after his death they said he had many interests and was "always there with a smile and cheeky sense of humour".

"He was a loving son, brother, nephew, grandson, friend and we will never recover from the loss and not having him in our lives."
