Two youths are being hunted by police after a fire was started on a train.

The young males were travelling on the Troon to Glasgow Central Station service at around 7.15pm on June 21.

Witnesses say they saw one of the youngsters setting fire to newspapers in the second coach. They then left the carriage.

The fire consumed part of a seat and the surrounding floor area before a member of the public got up and stamped out the fire.

Police say they want to speak to this man and anyone else who witnessed the incident.

The suspect is described as white and was wearing a white and blue Adidas tracksuit top and a navy blue baseball cap. He was carrying a football.

Anyone with information is asked to contact PC Darren McDonald at British Transport Police on 0800 405040.
