A panicked mum watched as a train pulled away from a station in Cambridge with her 22-month-old daughter on board.
Jasmin Stewart, 26, had taken her daughter Mia to the zoo at Shepreth with her partner when she got off the train and was holding the little girl's hand but the doors began to close.

The pair were separated and Jasmin frantically tried to open the door while passengers helped from the inside.
Speaking to Cambridge News, she said: "The train started to move. I was in blind panic and ran with the train banging on the door but, within seconds, it was out of sight. I was in complete bits. The next few minutes were a blur."
As the couple had got off at an unstaffed station there was no-one to ask for help.
The Mirror reports that they used the emergency telephone on the platform to contact the rail company which then radioed the train.
Train workers were alerted and Jasmin and her partner travelled to Royston to meet Mia who was in the company of two members of staff.
