Police are “intensively” focusing resources on the Deepings after a string of burglaries on homes in the area.
More than 20 incidents have been reported in the last three months, with many carried out while people are on holiday and their homes are empty.
Ten were burglaries and the rest were intruders who were disturbed without stealing anything or attempts to break into homes. When thieves did get in they stole TVs, laptops and computer games.
Police thought they had stopped the crime wave when they arrested and charged two men in July. But while they were in custody more homes were burgled.
The frequency of burglaries has slowed in the last couple of weeks. But police are still trying to find those responsible.
Sergeant Rachel Blackwell, based in Stamford, said: “We are very much focusing our resources on this intensively.
“This is peak holiday season. Often people have gone away and it’s obvious they are not home because there are no lights on.
“We would ask people to put their lights on a timer or ask their neighbours to keep an eye out if they know they are going to be away.”
Sgt Blackwell said the more recent incidents involved burglars breaking down doors or smashing windows to get into houses, so alarms and locks were not particularly effective.
Officers are following up certain leads but they are still keen to hear from any witnesses or anyone who may know anything about the burglaries.
Sgt Blackwell said: “We think the bulk are being committed by people travelling over from Peterborough, but there is nothing definitive to confirm that.
If you have any information on the burglaries, call police on 101.
