Police officers want to trace two men after a buffet bar on a train was broken into.
They believe the men, who were part of a group which boarded the 8.49pm Sheffield to St Pancras train on Christmas Eve, could help with inquiries.
PC Josh Dunn, of British Transport Police, said: “A group of approximately 12 men boarded the train at Chesterfield.
“Two members of the group broke the shutters on the buffet bar, which was closed at the time of the incident, pulled them up then climbed in and stole a number of items.”
Anyone with any information should call 0800 405040.
