Thieves escaped with a 42-inch TV set after using a ladder to climb through the bathroom window of a village flat on Christmas Day.
Police say they are investigating the theft of the £330 television from the lounge of the flat in Butts Meadow, Wisborough Green.
A spokesman said: “It is believed a ladder was used to gain access through an upstairs bathroom window some time between 10am and 10.30pm while the property was empty.”
Detective Constable Jon Tizzard added: “Nothing else was stolen from the property. I would like to hear from anyone who was in the area and who saw any suspicious activity.
“We are also keen to recover the television set which is described as a Panasonic Model TX40CX400B.”
