Police are hunting a street thug, who punched a young woman from behind as she waited at a pedestrian crossing early in the morning.
Detectives in Lambeth have released this CCTV image of a man they would like to speak to after the 25 year-old woman was punched in the head in an unprovoked attack.
The victim was waiting at a pedestrian crossing in Clapham High Street at 7.27am on Wednesday, September 14, last year.
The suspect then ran off towards Gauden Road.
Following the attack the victim flagged down police officers who carried out a search of the area.
They were unable to find the suspect.
The woman received minor injuries from the assault.
The suspect is described as a black man, aged between 30 and 40 years-old 6 foot-tall, with short black hair.
He was clean shaven or had short stubble and was wearing dark trousers and a green jacket.
No arrests have been made and enquires continue.
Detective Constable Dan Nash, from Lambeth CID, said: "The victim was simply going about her business when out of the blue a man approached her from behind and punched her in the side of her head before running off.
"This was an unprovoked attack which has left the victim very distressed.
“CCTV footage shows the man loitering at the location for a few minutes before the attack.
"Clapham High Street was very busy at the time of the incident. Someone must have seen something, so I am appealing for any witnesses or anyone who recognises the man to come forward."
