An elderly man is in a critical condition after he was knocked down by a moped rider whose gang then circled him before they “callously” rode off.
The victim, from the Kensal Rise area of north-west London, was hit by one of more than six mopeds at around 8.30pm on January 3 as he was crossing Harrow Road, the Metropolitan Police said.
The riders, wearing crash helmets, rode around him while he was on the ground and then drove off towards Wrottesley Road.
The victim, who is in his early 80s, was taken to a central London hospital where he remains in a critical condition.
His family have been informed and officers from the Met’s Serious Collision Investigation Unit are investigating.
Detective Constable Leo Christian said: “We are looking for any witnesses who saw the collision or the group of mopeds being ridden around the area.
“They callously rode off leaving an elderly man seriously injured in the road and did not even try to get him any help.
“We are determined to find those responsible and I would appeal to anyone who was part of this group of riders to do the right thing and come forward.”
Officers appealed for witnesses or dash cam footage that may have recorded the riders.
