A pensioner is punched to the ground and left unconscious in new CCTV footage of the London riots released by police.


Officers want to speak to anyone who saw the attack on the 69-year-old during the disturbances in the capital.
The retired teacher was attacked as he came out of branch of Ladbrokes in Enfield, East London on August 8.
He was shoved into the shutters of another shop before the suspect punched him in the stomach.
The punch sent him falling to the ground and knocked him unconscious.
The gang, one of whom had an Alsatian dog, then stepped over his prone body and entered the bookmakers.
Members of the public helped the man, before he was taken to hospital.
He received treatment for injuries to his eye, nose and lip.
The suspect is described as an Asian male aged approximately 16 to 20 wearing dark clothing.

Police said both assaults were unprovoked
The Metropolitan Police said the suspect then assaulted a second man around 10 minutes later.
He grabbed a man who appeared to be on his mobile phone around the neck.
However the second victim broke free, throwing his phone to the floor in the process which another member of the gang picked up and ran away with.
Officers want the victim to come forward and speak to police about the incident.
Acting Detective Inspector Ian Fleming of Newham borough CID said: "These were unprovoked attacks, one on an innocent elderly gentleman who sustained serious injuries and another on an innocent young man, both of whom were just going about their day-to-day activity.
"There would have been lots of people in the areas at the times of the incidents and I appeal for any witnesses to come forward and assist police in catching those responsible."
