A woman in Northampton was pushed in the face and splashed with a fluid her attacker claimed was acid.
The incident began at 2.35pm on July 28 in Arthur Street, Kingsley, when a woman challenged two women she was concerned could be taking advantage of an elderly male neighbour.
During the confrontation one of the two women pushed the victim in the face, before walking off into Barrack Road.
The altercation continued when one of the women threw the contents of a drinks bottle at the neighbour, saying it contained acid.
Some of the fluid hit the neighbour’s ankle but did not cause any harm, and it is not believed to have been a corrosive substance.
One of the suspects is described as a white woman aged in her 30s, around 5ft 6in and of slim build. She wore a navy blue jacket, black leggings and white trainers, and carried a large pink handbag and a white Tesco bag with red handle.
