Seven burglars smashed a window at the back of a house in Northampton but ran off after they were disturbed inside.
The gang broke into a home in Briton Road, Abington, between 5.45pm and 6pm on Friday.
The men forced entry to the house by smashing glass at the back of the property.
Once inside, two of them went up the stairs where they were confronted by the victim. All seven men then fled the scene.
One is described as a white man in his early 50s, with a “big belly”. He was wearing a white baseball cap and a green jumper.
Another offender is described as a white man in his early 20s, of skinny build. He was wearing tracksuit bottoms and a white striped hooded top.
No description is available for the other five men.
