A pensioner was left battered and bruised after being attacked on her own doorstep.
The Metropolitan Police have released image of Catherine Smith and her horrific injuries which she suffered in the robbery on July 27.
The 82-year-old was out in her mobility scooter walking her dog in Tulse Hill, south London, when she first saw the female suspect .
She left Palace Road Nature Gardens with her dog to return home at about 1pm, and when she arrived she saw the suspect sitting on a wall outside her property.
The woman approached the victim and said "where's Tracey" before repeatedly asking for money.
Catherine said she did not know a Tracey. The suspect then asked Catherine if she could use her toilet, and the victim said no.
As she tried to close the door to her home, the suspect forced the door open causing Catherine to fall backwards and hit her head.
There was a struggle and the suspect proceeded to punch Catherine in the head and then grabbed the victim's dog lead, wrapped it round her neck and started to strangle her before running away.
Catherine called for help and witnesses rushed to her aid, saw her covered in blood and called the police. She was treated in hospital and has since been released.
The suspect is described as a black female, about 5ft 5ins, of slim build, with slick-backed black hair.
She was wearing a khaki coloured coat with a zip, multi-coloured trainers and tights.
