Grinning riot suspect seen on CCTV
Grinning into the camera, this riot suspect may not be smiling for long after finding out he is wanted by police.
The man - who published the picture of himself on Twitter - joins dozens of mugshots and CCTV images of suspected troublemakers being hunted by police in London and Manchester.
Both Scotland Yard and Greater Manchester Police have released fresh batches of images.
New pictures released by the Metropolitan Police relate to looting and violent disorder in Tottenham, Haringey and Wood Green on Saturday. Nine other men are pictured in the latest gallery of suspects in London.
In Manchester, 17 CCTV images were issued.
Greater Manchester Police Chief Constable Peter Fahy said the pictures are "just a few" of the images captured on CCTV and by other means.
"We have a huge amount of other material, we already are at this very moment preparing to go out and arrest individuals," Mr Fahy said.
"We have had at least one individual give himself up because his picture is on Facebook committing crime."
