A teenager who tried to break into his own house in Long Buckby after forgetting his keys inadvertently triggered a response form an tactical police unit and sniffer dogs.
A concerned neighbour dialled 999 at around 11am this morning when she saw a man appear to break into a house in Marriots Road.
A quarter mile area around the road has recently been hit by three burglaries in the past week.
Within 10 minutes eight officers from across the county were scrambled to Long Buckby, with squad cars positioned at strategic exit points around Marriots Road.
A sniffer dog unit was also called to the scene to track down any would-be fleeing burglar.
But when officers knocked on the door of the house, it emerged the 18-year-old who broke into the property lived there, and had simply forgotten his keys.
Sgt Sam Dobbs of the Daventry Safer Community Team, thanked the 999 caller.
He said: “We are really pleased with the woman, she did the right thing as there have ben three burglaries in the past two weeks.
“Officers were quickly on the scene to contain the area.
“They were supported by a dog unit and the East Midlands Special Operations unit.
“Had it been a suspicious incident we would have got the person we were looking for.”
