A MAN has touched himself inappropriately in front of a woman on a Glasgow-bound train.

British Transport Cops are hunting for the pervert who struck at around 7am on Wednesday on board a Gourock to Glasgow Central service.

The force said a man made prolonged eye contact with a 28-year-old woman before beginning to touch himself inappropriately, as the train left Paisley Gilmour station.

It is believed that the suspect left the train at the next station.

He is described as between 55 and 70 years of age, white and of skinny build and with thin white hair. He was wearing a flat cap, blue jeans, a black waterproof jacket and was carrying a black backpack.
