Britons swept up, patched up and feared further violence on Tuesday, demanding police do more to protect them after three nights of rioting left looted stores, torched cars and blackened buildings across London and several other U.K. cities.
In Clapham, a south London suburb, hundreds of volunteers gathered to clean the streets with brooms.
"These riots have been really awful and we just want to show our support for the community because everyone needs help to get back on their feet," one volunteer, 15 year old Issy Krupski said.
London''s Metropolitan Police force have vowed an unprecedented operation to stop more rioting, flooding the streets on Tuesday with 16,000 officers, nearly three times Monday''s total.
Although the riots started on Saturday with a protest over a police shooting, they have morphed into a general lawlessness that police have struggled to halt with ordinary tactics.
"I understand that there are calls for all sorts of measures including the army and I just want to stress that we have a system in this city and in this country of robust but consensual policing and that is what we propose to stick with," London''s mayor Boris Johnson said on a visit to the clean up.
Police in Britain generally avoid tear gas, water cannons or other strong-arm riot measures. Many shops targeted by looters had goods that youths would want anyway - sneakers, bikes, electronics, leather goods - while other buildings were torched apparently just for the fun of seeing something burn.
Police said plastic bullets were "one of the tactics" being considered to stop the looting. The bullets were common in Northern Ireland during its years of unrest but have never before been used in mainland Britain.
But police acknowledged they could not guarantee there would be no more violence. Stores, offices and nursery schools in several parts of London closed early amid fears of fresh rioting Tuesday night, though pubs and restaurants were open.
