Images have been released of two youths wanted by police after an elderly man was attacked and pushed to the floor.
Detectives believe the two suspects, caught on CCTV, may have followed the 77-year-old victim from Manchester to Salford before robbing him.
The pensioner was waiting outside the Tesco store at the Ellesmere shopping centre in Walkden when two young men approached him.
After asking him if he waiting for a taxi, they pushed him to the floor, assaulted him and stole items from his pockets, including a mobile phone.
The victim, who has not been identified, suffered a cut to his hand and extreme shock.
Police believe the two offenders earlier planned their attack after seeing the victim at a bookmakers’ in Piccadilly, Manchester and following him out.
