British Transport Police officers are appealing for witnesses to a sexual assault on a train from Edinburgh to Aberdeen to come forward.

The incident took place between 9pm and 9.30pm on Sunday 24 August, on a train from Edinburgh Waverley to Aberdeen when a 15-year-old girl was sexually assaulted by a man in his 40s.

The man was described as white in his 40s or 50s, around 5ft10 with short dirty blond hair. He was wearing a pink shirt and beige shorts.

Officers would like to speak to the members of the public who intervened, as they may have information that would help their investigation.
