A 65-year-old woman was threatened with a hammer and had jewellery and passports stolen from her Northampton home.
A man knocked at the property, in Coneywell Court, Standens Barn, between 9.10pm and 9.20pm on Tuesday, January 20 claiming to be from the gas board.
He stated that there was a leak and that the victim needed to leave.
Two other men then joined the offender and they forced their way into the property.
One of the offenders held the victim down, threatening her with a hammer, while the others ransacked the house.
Jewellery and passports were stolen.
The offenders were disturbed by the victim’s son returning, prompting them to run from the house. As they left, one of them used the hammer to smash the rear window of the son’s car.
They got into an old looking, dark coloured, vehicle which reversed out of the street at speed without any lights on.
The offender with the hammer is described as a white man, around 6ft 2ins tall, of stocky build, 45 – 50 years old and with light brown hair. He was wearing dark blue sports clothing and a cap. He spoke with an Eastern European accent.
The other two offenders are described as white men, around 5ft 4ins tall, of muscular build and wearing dark blue jogging clothes.
