A passenger was forced to tweet Southeastern rail staff for help after he was locked in the toilets of a train.

Steven Staples sent the tweet for help from the toilets of the 7.38am service from London Blackfriars to Orpington.

Mr Staples, 38-years-old, said: "I locked it but it wouldn't unlock again after, I tried a credit card, but didn't want to break it so turned to Twitter."
