Thieves forced open a caravan window and stole a flat-screen TV.
The incident happened sometime between 11pm on Tuesday and 11am on Wednesday.
The caravan was parked within the South Links Caravan Park in Montrose.
Police say that the culprit could have been spotted carrying the 32-in screen away from the caravan.
A spokesman for Police Scotland said: “Although the area of the park that the caravan was situated in is fairly secluded, it is possible that the person(s) responsible may have been seen carrying the stolen item, or perhaps they could have been in the park earlier in the day.
“If you have any information which could assist our enquiries, please call 101 or speak to any Police officer.
