British Transport Police officers are asking for witnesses to come forward following reports of a man exposing himself in public at Chepstow railway station.
The incident took place on Wednesday 1 February at about 12.05pm.
Two teenage girls witnessed a man masturbating on the pedestrian footbridge overlooking the station platforms and proceeded to inform the train guard of the Cardiff-bound service.
When trying to board the train, the man was questioned by the train guard and then refused travel.
That evening, a 25-year-old man was arrested for Outraging Public Decency and was later released on conditional police bail pending further investigation.
