A woman was subjected to a “frightening” sexual assault on a train to Blackpool, police have said.
The 50-year-old woman was travelling from Accrington to Blackpool North when a man began to touch her legs and make suggestive comments to her.
Despite locking herself in the toilet to avoid the man, he waited for her to come out.
As the train arrived at Blackpool North station, she managed to escape by pushing past him.
Police are now appealing for information about the incident, which happened between 8.30pm and 9.30pm on November 28.
PC Adam Heslop, of British Transport Police, said: “As the train left Accrington a man sat opposite the woman and began to touch her legs.
“She told him to stop, which he did, but as the train left Preston he touched her again and made suggestive comments to her.
“She tried to move away from the man – towards the centre of the train – but he followed her and touched her inappropriately.
“The victim managed to lock herself in the toilet of the train, but the man waited for her to come out. Fortunately she was able to force her way past him and subsequently got off the train at Blackpool North where she informed BTP of the incident.
“This was, without doubt, a frightening experience for the woman and I am now asking anyone with information about the incident to get in touch.
“Thankfully sexual assaults are rare on the rail network, but we cannot afford to be complacent and we will do everything in our power to bring offenders to justice.”
Anyone with information is asked to call British Transport Police on 0800 405040 or ring Crimestoppers anonymously on 0800 555 111, quoting log PSUB/B2 of December 4.
