Police say Leeds riot 'premeditated'
Two dozen cars and a shop were set on fire when a seven hour riot broke out on the streets ofLeeds on  Tuesday night.

It is thought the violence by mainly Asian youths may be related to the arrest of an Asian man on Sunday.

But Assistant Chief Constable of West Yorkshire Police Graham Maxwell said the rioting was "criminal activity, pure and simple. He described it as "a premeditated attack on police".
