A fourth person has been arrested on suspicion of murdering Alan Cartwright, the schoolboy who was stabbed to death while riding a bicycle with his friends.

Scotland Yard said an 18-year-old man was arrested on Thursday morning after attending a north London police station.

Another 18-year-old man was arrested early on Wednesday after also attending a north London police station. A 17-year-old boy and a 21-year-old man were arrested in Camden on Wednesday morning.

Police said the three adult suspects remain in custody while the 17-year-old has been bailed to a date in mid-April.

The arrests follow an appeal by Alan’s family for witnesses to come forward to help track down the 15-year-old’s killers. Police released footage of the moment the boy was stabbed in the chest as he cycled with friends along a busy road in Islington.

He managed to continue riding a short distance after the attack in Caledonian Road on Friday, but collapsed and was later pronounced dead at the scene.

A second suspect is shown lunging at one of the teenager’s friends and knocking him off his bike, while a third crosses the road and grabs another friend to pull him off his bicycle. A post-mortem examination found that Alan died from a single stab wound to the chest.

His mother and sister described the army cadet and Celtic and Arsenal fan as a “joker” who loved bikes and never caused any trouble.

During an appeal on Tuesday, Alan’s mother, Michelle Watson, 39, said: “He always made you laugh about anything and everything. He was just the funny one out of his friends.

“I feel angry, I want somebody found for this.”
