A 34-year-old man sought by police investigating a car crash that killed three teenagers has been arrested.

The Metropolitan Police said the man handed himself in at a police station, in connection with the crash in Hayes, west London at about 20:40 GMT on Friday night.

Police said the suspect has been arrested on suspicion of causing death by dangerous driving.

Detectives also named the victims of the fatal crash as 17-year-old Harry Louis Rice, 16-year-old George Toby Wilkinson and 16-year-old Josh Mcgunniess.
