Two people have been killed after their car was hit by a vehicle fleeing from police in Leeds.
West Yorkshire Police said it happened at 00:44 GMT, when a blue BMW 123D failed to stop for officers in Gelderd Road and then crashed into a white Volkswagen Scirocco.
The driver of the Volkswagen, a 22-year-old man, died at the scene. His passenger, a woman, 23, died later in hospital. Both were from York.
The occupants of the BMW, a 39-year-old man from Harrogate, two boys aged 16 and 17 and a 16-year-old girl, have been arrested on suspicion of causing death by dangerous driving.
The 39-year-old is also being held on suspicion of driving while over the prescribed limit for cannabis, the force confirmed.
The teenagers in the BMW were taken to hospital for treatment to injuries that were not considered life-threatening.
A spokesperson for West Yorkshire Police said a referral had been made to the Independent Office for Police Conduct, which would conduct an independent investigation.
