A six-year-old boy has died in hospital after a hit-and-run crash that killed his two-year-old brother.
The children were hit by a car in the Stoke area of Coventry at around 2pm on Thursday.
Both children died after being taken to hospital.
A black Ford Focus was found abandoned a short time after the crash with the front right side smashed in and the front windscreen smashed.
West Midlands Police have arrested a man and a woman following the crash on MacDonald Road.
A 53-year-old man and a 41-year-old woman are being held on suspicion of causing death by dangerous driving and drink driving.
The road is closed as police speak to witnesses and emergency services attend.
Police said: "Our thoughts and sincere condolences are with the family of the two boys."
One person who lives near the crash scene said they had seen a "smashed" pushchair in the road by the side of a child's scooter.
"The police had taped the road off and there was debris all over the road," said the woman, who asked to remain anonymous.
She added: "I was advised not to go near as the kids were still on the road and I had my young girls. It was very sad to see."
Earlier, detective sergeant Paul Hughes said: "We are still trying to establish how this tragic incident has happened and anyone who hasn't yet spoken to an officer should call us on 101.
