British Transport Police have launched an appeal for witnesses after a child was sexually assaulted onboard a train bound for Glasgow.

At around 10.20am on Tuesday, July 25, the 12-year-old victim was travelling with her mother and sister on the 10.08am service from Balloch to Airdrie when she was sexually assaulted by a man. 

The man was described to be white, of medium build and average height, with short greyish hair and wearing a black face mask that partially covered his face.  

He was wearing a black hooded jacket, black bottoms with a red stripe down the leg, and black Nike trainers. He was carrying a black bin liner and a black rucksack.  

He is believed to have boarded the train at Dumbarton Central and got off at Old Kilpatrick station.  

Officers believe a person sat nearby may have witnessed the assault and are appealing for them to come forward and assist the investigation.
