Police investigating the riots that swept London in August have posted photos of more than 200 suspects online in an effort to bring those involved in the disorder to justice.
Gangs of masked youths burnt and looted city neighbourhoods, leaving five people dead, in the worst unrest for a generation.
Police have already arrested 3,269 people, of which 2,046 have been being charged or summonsed, while at least 3,877 crimes have been reported.
Now officers, who have scoured 200,000 hours of CCTV footage, hope the release of new images will lead to further arrests before Christmas.
Commander Steve Rodhouse, leading the riots investigation dubbed Operation Withern, urged people to come forward with information which could assist inquiries.
"Four months on from the disorder my team of officers remain absolutely committed to identifying, arresting and charging those involved in the criminality that took place," he said.
"The investigation is a huge challenge and one that will continue for some time to come, but I want to reassure London's communities that we are determined to bring those who committed these outrageous crimes to justice and more arrests will follow."
All 213 images can be found on the Metropolitan Police Service's Flickr page along with previously released images.
Anyone who recognises a picture or has any information can contact Crimestoppers anonymously on 0800 555 111, quoting the reference number alongside the image.
As well as the police effort, the riots also spawned unofficial websites aimed at tracking down those behind the unrest, with names such as "Catch A Looter."
