The acting police commissioner in London says there are no plans to call in the military to help beleaguered police restore order in London and other British cities hit by rioting.
Acting Police Commissioner Tim Godwin spoke after leaving an emergency meeting.
He also called on parents to keep their teenagers and children indoors as the capital braced for another day of unrest.
British Prime Minister David Cameron announced that 16,000 officers would be on the streets of the capital Tuesday night — almost tripling the number on the streets Monday night.
"People should be in no doubt that we will do everything necessary to restore order to Britain's streets and to make them safe for the law-abiding," Cameron told reporters after a crisis meeting at his Downing Street office.
A wave of violence and looting raged across London, as authorities struggled to contain the country's worst unrest since race riots set the capital ablaze in the 1980s. Some 450 arrests have been made.
