Police in London said Friday they have charged almost 600 people with violence, disorder and looting over deadly riots in London, as the city’s mayor said he wants to see “significant sentences” handed out to the guilty, according to The Huffington Post.

The Web site reported that across the country, more than 1,700 people have been arrested. Courts in London, Birmingham and Manchester stayed open through a second night to deal with hundreds of alleged offenders.

Hundreds of stores were looted, buildings were set on fire. Several people died during the riots that broke out Saturday in London and spread over four nights across England. Three men in Birmingham were run down by a car as they defended their neighborhood.
