ACID House revellers pelted police with bricks and bottles and set a police car ablaze in a midnight riot.
At the height of the violence, police officers in riot gear were set upon with metal bars, fire extinguishers, bricks and bottles as they tried to prevent 2,000 revellers from taking over a semi-derelict factory in Blackburn.
A police chief later called it "a sustained, unprovoked attack".
