Detectives investigating a bag-snatch are appealing for witnesses and information about the suspect, and for a member of the public who stopped to help the victim to come forward.

The victim, a 63-year-old woman, suffered a serious head injury after a man wrestled her handbag from her arms, knocking her to the ground.

The robbery happened at around 20:45hrs on Sunday, 5 May on Camley Street, N1.

The suspect ran away. The victim alerted a member of the public who was on a motorbike, who went after the suspect. He got the handbag back and gave it to the victim before riding off.

The victim was later taken to hospital and has since been discharged.

No arrest has been made to date, and officers are appealing for information about both the suspect, and the member of the public who chased after the suspect and is potentially a significant witness.

The suspect is described as a white man, aged in his mid-20s, around 5ft 7ins tall and of slim build with black, messy hair and a short beard. He was said to be wearing a matching black or navy blue tracksuit with a hooded top, and a white T-shirt.

Detective Constable Stuart Douglas, of the Central North BCU, said: “This was an opportunistic robbery which resulted in the victim sustaining a nasty head injury. She is thankfully making a good recovery, but we need to find the person behind this attack. If you were in the area at the time and remember seeing a person matching this description or anything suspicious, get in touch.

“We are also keen to locate the man who stopped to help the injured victim, and even got her bag back for her. His information could be important to our investigation.”
