A distraught mum was left behind on a London tube platform as a train sped away with her sleeping baby on board.
The mum, said to be in her late 20s, had put the baby's pram on the train at South Kensington station, but the doors closed before she could get on herself.
The Circle Line train then pulled away despite other passengers pulling the emergency cord once they realised what had happened.
The train briefly stopped, but the driver announced he had to carry on to the next station, Gloucester Road.
The distressed mum was escorted to the station where she was reunited with her baby.
Malcolm Dyer, 59, from Ascot, told the BBC he had witnessed the entire incident, and that the tiny passenger slept throughout the ordeal.
"She pushed the pram on and all of a sudden the doors shut on to her hands, so she naturally let go and left the baby on there and the train started moving," Mr Dyer said. "I shouted at someone to pull the alarm, which they did and the train stopped momentarily. The baby was merrily sleeping, unaware of anything that had happened."
"She was a bit silly trying to put a pram and herself on the train when the beeps were indicating the doors were closing, which I wasn't happy with, but these things happen," he added.
Staff from South Kensington phoned ahead to Gloucester Road, and Mr Dyer and two other passengers took the baby off the train to meet its mother.
Pete Allaway, Circle and Hammersmith line manager, praised his staff and the passengers who looked after the baby.
"I'd like to thank the quick-thinking actions of our staff who acted in a calm, professional manner throughout, and I'd also like to thank the customers on the train who alerted the driver and stayed with the baby until the train could be met by station staff," he said.
