A police station in Nottingham was firebombed late on Tuesday by a group of up to 40 men, police said, while there was looting in Manchester and there were tense scenes in Salford.
Canning Circus police station in Nottingham was attacked by the group but no injuries were reported, Nottinghamshire police said just after 10pm.
The force said a number of men were detained nearby.
There was also trouble in Birmingham and other parts of the West Midlands, but relative calm in London as Scotland Yard attempted to put the capital in lockdown with 16,000 police on the streets, in contrast to 6,000 on Monday.
