UK cops come knocking to arrest London rioters

One by one, rioters who ran amok on the streets of London and other cities are being arrested as police officials, aided by CCTV images, came knocking on doors from this morning even as courts sat through the night to dispense justice expeditiously.

As prime minister David Cameron declared in the House of Commons today, "We will track you down, we will find you, we will charge you, we will punish you. You will pay for what you have done."

Among those who participated in the rioting is an 11-year-old girl in Nottingham, reflecting the fact that most of those responsible were in their teens or younger.

Those arrested included youngsters who attend grammar schools or are employed. More than 100 arrest warrants were executed out today morning in London, the police said.

Arrests and speedy delivery of justice were also taking place in other riot-hit towns such as Birmingham, Nottingham and Manchester.

Stephen Kavanagh, Metropolitan Police's deputy assistant commissioner, said some of his colleagues were disappointed with the light sentences given to looters so far.

He told BBC: "That has been personally raised by me and others, and the commissioner I know has also raised it, so we will move through those issues and I am confident we will get the support of the courts."

He said the huge policing presence on the streets would continue for another night, and would then be reviewed.
