Around £2,000 of toys, clothes and other gifts were stolen by thieves who targeted a family home in Oxford on Christmas Eve.
The offenders broke into the property in Walton Street between 1.30am and 7am and discovered a stash of presents in an unoccupied bedroom, which included children's games, food and bathroom products.
Officers from Thames Valley Police are investigating the burglary, with the thieves having left the wrapping paper in the street after making off with the items.

"Offenders would have been carrying five large bags of items around the area at an unusual time of day. Christmas presents were opened and wrapping paper dropped in the street following the burglary.
