An illegal Halloween rave in central London lasted six hours before being shutdown by the police.
Skirmishes broke out between police and revellers on Saturday night, after officers attempted to prevent hundreds of people from entering the event in Lambeth.
The Met said eight people were arrested during clashes that went on through the night. The rave, which was advertised on Facebook as Scumoween: A Nightmare On Scum Street, was finally closed down at 6am.
Videos posted to YouTube captured violent confrontations between line of riot police and ravers.
