LONDON — Police here said today they have charged almost 600 people with violence, disorder and looting over deadly riots in Britain’s capital, as the city’s mayor said Londoners wanted to see “significant sentences” handed out to the guilty.

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 ablaze and several people died amid the mayhem that broke out Saturday in London and spread over four nights across England.

Victims include three men in Birmingham run down by a car as they defended their neighborhood. Police are questioning three suspects on suspicion of murder.

And detectives opened a murder inquiry after a 68-year-old man found in a London street after confronting rioters died of his injuries late Thursday. A 22-year-old man was arrested today on suspicion of murder.
