Police have launched a series of raids in a major swoop on suspected summer rioters, Scotland Yard has said.
Search warrants were executed at around 100 addresses across London in the early hours of Wednesday in a bid to arrest those involved in the August disturbances.
The Metropolitan Police said the public had helped to identify many of the suspects wanted over the violence and disorder seen across the capital.
Detective Superintendent Robin Bhairam said: "Today's activity is an indication that, four months on from the incidents seen across London, we remain absolutely committed to identifying and arresting those responsible for the disorder.
"Following on from the release of over 200 suspect images on Flickr as part of the Winter Withern Campaign, I would like to thank all those who have responded to our appeal in helping us to identify those wanted.
"A number of people have been identified and inquiries are still ongoing. There are still a number of people we wish to speak with and I would encourage anyone who has any information to please let us know."
A 17-year-old boy was arrested at a flat in Hackney, east London, on suspicion of violent disorder. The teenager, who is believed to have thrown bricks at police during the riots, was woken by officers at around 6.30am and led out of his flat in handcuffs.
Mr Bhairam added: "Searches like those carried out today are happening on a daily basis and my message to those who were involved in criminality is that you will not get away with it.
"We have a huge team of dedicated officers working on this investigation and we will find you. We are determined to bring those who committed these outrageous acts of criminality to justice and we will continue to make arrests."
Four months on from the disorder the Met has made 3,423 arrests for a variety of offences and 2,179 people have been charged or summonsed.
