The second man was wearing a black T-shirt and shorts and had a dark-coloured beard.

Investigating officer PC Colin Campbell said: “This type of aggressive behaviour is totally unacceptable and will not be tolerated. The girls were obviously left very shaken by the incident, which was completely unprovoked.

“I urge anyone who was in the station at the time, or travelling onboard the train, to come forward and help us bring these men to justice.”

Anyone with information is asked to contact British Transport Police on 0800 40 50 40 or text 61016, quoting 399 of 10/9.
