Five people, three of them children, have died after a stolen car crashed in Leeds, West Yorkshire Police said.
Police said they found a "complete carnage" scene when they arrived on Stonegate Road in the Meanwood area of the city on Saturday night and discovered that a Renault Clio had crashed into a tree.
A 12-year-old boy, two 15-year-old boys, a 24-year-old man and a 28-year-old died in the collision.
Two 15-year-old boys have been arrested on suspicion of causing death by dangerous driving and remain in custody.
A West Yorkshire Police spokesman said that while only one vehicle was involved, it was not yet clear if the victims and suspects were all in the car.
