A 23-month-old baby and a 10-year-old child have died in a hit-and-run car crash in the west Midlands.
An Audi A3 struck a BMW carrying the two children and their mother in Birmingham New Road, Wolverhampton.
The children were pronounced dead at the scene. The woman sustained serious injuries and was taken to hospital, where she remained on Friday.
The driver of the Audi left the scene.
A 31-year-old man from a third car, a Bentley, was arrested at the scene on suspicion of causing death by dangerous driving. He remained in custody on Friday.
The crash happened at about 9pm on Thursday.
One man, who lives nearby, told the Press Association: "There were car seats in the back. It was completely written off with the airbags deployed.
"There was a man lying in the road and he looked injured, and I heard a woman screaming about 10 minutes after it had happened.
"It's very sad to hear that children have been killed."
Det Sgt Paul Hughes, from West Midlands Police's serious collision investigation unit, said: “This is an extremely tragic set of circumstances which has left a family totally devastated. Staff from our dedicated family liaison unit are now supporting them.
“I would appeal directly to the driver of the Audi to make contact with us. You may not be fully aware of the full tragic circumstances but you now need to speak to us.
“I would also ask the public who have any information or recall seeing a blue Audi S3 and a white Bentley Continental convertible travelling along the Birmingham New Road to make contact.
“The investigation is in its early stages and I would also ask the public to think about the family at this tragic time and not to speculate on the circumstances surrounding the collision.”
