Civil unrest is growing in London as fresh riots, lootings and raging fires continue on Monday following Saturday's incident in gritty Tottenham.

Hundreds of teens are looting shops, lighting fire to business places and continue to clash with police in at six neighborhoods, according to reports.

These riots are particularly damaging for the country, as it is less than one year away from the start of the Olympics.

The Metropolitan Police has launched an investigation into the Tottenham riot, which resulted into two being attacked along with reports of fires and looting.

The BBC reported that officers on the inquiry, named Operation Withern, will interview witnesses and review hours of CCTV footage in order to identify rioters.

About 55 people were arrested during the riot and are being questioned.

The riot followed a demonstration by members of the community outside Tottenham police station demanding "justice" for Mark Duggan, a 29-year-old father of four, who was shot after police stopped the minicab he was driving in.

Since then, clashes have broken out in Enfield, north London, where shop windows have been smashed and a police car damaged, according to the BBC, and riot police were deployed to the area.

Police have said "several arrests" had been made after shops were vandalized.

Prime Minister David Cameron has cut short a vacation trip to Tuscany and will return to London on Monday night to chair an emergency cabinet meeting on how to handle the escalating crisis.

"Nobody should go out on the streets unless they have business to do so," Simon Hughes, a national lawmaker from an inner London neighborhood, told reporters, as reported by the Los Angeles Times.

The unrest is partly through mobile BlackBerry texts, Twitter and other social networking sites, and is taking root in poorer neighborhoods that are away from the central heart of London where vacationers tend to stay.
