A CCTV image has been released by British Transport Police in connection with a theft on a train to Edinburgh Waverley Station.
Personal property and a sum of cash was stolen from a passenger travelling on the 16.28 Dunblane to Edinburgh service on Saturday, December 19.
Officers believe the man pictured in the footage will be able to assist with their investigation.
He alighted from the train shortly after 5.35pm.
