Detectives swoop on Camden home and arrest 21-year-old

A third arrest has been made by detectives investigating the death of 15-year-old Alan Cartwright.

The 21-year-old was arrested on suspicion of murder this morning at a home in Camden. He is in custody at a central London police station.

Alan, 15, was knifed while cycling along Caledonian Road, with friends at about 7pm on Friday.

He managed to continue cycling a short distance after the callous attack but soon collapsed and was pronounced dead at the scene later.

In the early hours of this morning an 18-year-old man was arrested, then later a 17-year-old boy at an address in Camden.

Both were arrested on suspicion of murder and remain in custody.

Enquiries by Homicide and Major Crime Command detectives continue.
