Police are hunting two boys who set fire to a train seat - causing almost £5000 worth of damage.

The pair, who are believed to be aged around 12 or 13, also pressed the train's emergency button, causing delays for passengers on board the Balloch to Airdrie service between 9.40am and 10.10am on Wednesday, April 3.

The boys got off the train at Dalmuir railway station in West Dunbartonshire, where they got into a confrontation with a person who refused to allow them to rejoin the service.

A British Transport Police (BTP) spokesperson said: "Officers would like to speak to anyone who witnessed the incident.

"They would especially like to speak to the person who attempted to stop the suspects from boarding the train, and another person who filmed the suspects on their phone at Dalmuir station."
