Thieves have broken in to 17 properties in Kettering in the space of two weeks.
The spate of burglaries took place between Friday, April 26, and Friday, May 3, and has prompted police to issue a warning to people living in the town.
Officers are paying particular attention to the east side of Kettering and are distributing crime prevention advice and patrolling hotspot locations, including Pipers Hill, Avondale, Grange and Ise Lodge.
Detective Constable Sarah Bertram from the Kettering Town Safer Community Team said: “In the burglaries reported to us in recent weeks, thieves have stolen electrical items, jewellery, laptops and mobile phones.
“As always, we encourage people to make sure valuable items cannot be seen or reached through doors and windows, so that a potential thief passing by isn’t tempted by an expensive item left on display or in easy reach.
“With warmer weather upon us, we often see an increase in burglaries where an offender gains access through an open window or unlocked door.
“This has happened in three burglaries in the last two weeks.
“We have also seen one burglary where the offender has gained entry by reaching through a cat flap and turning a key that had been left in the door.
“We urge people to take simple precautions to reduce the risk of their home being a thief’s next target.
“Keep windows shut and doors locked, and make sure keys are not left in the lock.”
