A woman was injured after two men pulled her from her mobility scooter in an attempted robbery in Wellington Street, Northampton town centre.
The incident happened on Thursday, 2 June, between 2.45pm and 3.15pm when two men approached the woman and demanded she give them her handbag.
The men then attempted to pull her bag from the scooter but were unable to, at which point they pulled the woman and her scooter, causing her to fall.
The victim, who was in her 50s, suffered significant bruising to her side, arm and face.
The men are both described as white and in their late teens, with slim builds and dark brown hair. Both were wearing jeans and one of the men was wearing a white T-shirt.
Police are appealing for witnesses and would particularly like to speak to two young people who helped the woman get back on her scooter, as it is believed they may have seen the offenders leaving the area.
Anyone with any information is asked to Northamptonshire Police on 101. Alternatively, they can call the independent charity Crimestoppers anonymously on 0800 555 111.
