A woman was assaulted and had her handbag stolen in a robbery in Colyers Avenue, Corby, in the early hours of Sunday, 4 June.
Between 1am and 1.30am, the victim, a woman in her fifties, was walking along the road between Northbrook and Highbrook when she was approached by a man who asked for a cigarette.
The man then made an unsuccessful attempt to grab her handbag, at which point he punched her in the face causing her to fall. He then grabbed the handbag, pulling the woman along the floor causing her to let go of the bag. He ran off towards Gainsborough Road.
The offender is described as being about 5ft 3in, with a slim build and an English accent. He was wearing a white hooded top and blue jeans.
Officers are appealing for witnesses and would particularly like to speak to any taxi drivers who were in the area at the time and may have dash-cam recorders in their vehicles.
