Police are searching for ‘a male in his early 20s’ in connection with a burglary at a house in North Willingham, between Louth and Market Rasen.
Police say the man was seen to enter the driveway of the house before the burglary took place between 1.45pm and 4pm on Thursday, June 6.
Nearby house to house enquiries have also led the police to look for a silver 05 plate Ford Mondeo estate car which they say may have been involved.
Entry was gained to the house by kicking the bottom panel of the wooden back door and money and jewellery were taken after an untidy search.
Police say the man they are looking for is aged in his early 20s, around five feet eight inches tall with dark hair.
He was carrying a handful of paperwork, possibly leaflets.
Anyone with information should call police on 101 quoting incident 267 of June 6.
