TRANSPORT police are investigating an assault on a southside train in which a teenager was left needing hospital treatment.
The incident occurred on Saturday around 4.42, on board a train travelling between Glasgow and Barrhead stations.
Police said the 16-year-old boy asked four men to stop singing sectarian songs, at which point the group attacked him.
The youth was punched on the head and body and, according to police, a bottle was thrown and smashed during the fight.
The four attackers left the train at Barrhead station, and were last seen heading in the direction of Carlibar Road.
The victim was taken by ambulance to the Royal Alexandra hospital, and was later released after treatment for cuts to his head and face.
British transport police officers have been investigating CCTV footage of the incident, and ask any witnesses to come forward.
One of the four men was wearing a grey striped football top with green sleeves. Another is described as around 6ft tall with blond hair.
The third, wearing a green and white football top, black tracksuit bottoms and trainers, has short brown hair, is about 5ft 8 and of heavy build. The fourth is said to be 5ft 11, thin, with short brown hair – he was wearing a black jacket and navy trousers.
