A baby has been born in the back of a police car in Reading.
Thames Valley Police spread news of the arrival via Twitter.
Officers were on their way to Royal Berkshire Hospital on an unrelated matter just before 15:00 GMT when a couple stuck in heavy traffic "caught their attention", a spokeswoman said.
The man explained the woman was in labour and she was taken to hospital in a police patrol car but gave birth on the way.
Boy or girl?
The police tweet read: "A baby was born in one of our police cars today as PCs Ian Sullivan, Holly Galvin and George Wigley helped a woman on her way to hospital."
The spokeswoman said the force did not yet know whether the baby was a boy or a girl, but was awaiting news.
She said the couple were close to The Oracle shopping centre when they were spotted by police.
"Officers quickly assisted the woman and put her in the back of a patrol car to take her to the hospital," she said.
"After a couple of minutes they arrived at Royal Berkshire Hospital, opened the back door and the woman had already had her baby."
She said the officers had taken no credit for the delivery, and added medical staff from the hospital came out to help.
