A 100-year-old woman suffered a broken neck when her handbag was stolen by a thief who approached her from behind and knocked her over.
The victim is recovering in hospital after the "particularly nasty" broad daylight attack in Derby.
Police said her injuries are "not believed to be life threatening at this time". She is also being treated for facial bruising.
Detectives have appealed for information on the mugging, as the elderly woman was unable to give a description of the robber.
Detective Sergeant Laura Kershaw police are "particularly keen to speak to anyone who may have seen anyone with a bag matching the one pictured in any suspicious circumstances."
The stolen green fake leather bag with gold clasps was found around half a mile away at the junction of Moore Street and Normanton Road.
Police are appealing for CCTV or dash cam footage of the incident or of the robber with the bag.
