A woman in Daventry was assaulted in her own home after two men came knocking at the door.
The incident happened between 9.45pm and 10.15pm on Wednesday December 16 in Farnborough Drive, on Daventry’s Middlemore estate.
Police say two men knocked at her door and asked for money, but she refused and tried to close the door.
Both men then pushed the door open, knocking the woman to the floor. The woman was then attacked by one of the men, leaving her unconscious and with facial injuries which needed hospital treatment.
The men then stole money from the kitchen and fled.
Pc James Harvey, who is leading the investigation into the attack, said: “Fortunately incidents of this nature are very rare in Northamptonshire, but I would urge anyone who knows anything about this very nasty attack to come forward.
“These men have left this woman very shaken and we need to make sure they are caught and prevented from doing anything similar to anybody else.
“I would also remind home owners that they do not have to open their door to unexpected callers - it is not rude to send people away.”
Both of the men who attacked the woman were white, in their mid-to-late 30s and are thought to have been eastern European.
The first man was of medium to stocky build, about 5ft 8in with dark cropped hair. He had a strong accent and was wearing a light-grey hooded cardigan which had a zip down the front.
The second man was of slight to medium build, was under 5ft 8in and had mousey brown, collar length, hair which was messy.
