Hundreds flocked to an illegal rave at an abandoned Toys R Us store in west London.
The unlicensed event was held in the closed down store - and somebody even spray-painted over the original Toys R Us sign - so it read 'Raves R Us.'
A photo of the vandalised sign was posted by the Met Police on social media after the illegal gathering in Hounslow, was shut down.
Officers seized a sound system and arrested five people at the scene on the Bull's Bridge Industrial Estate.
The American toy company has been running a closing down sale since the UK arm of the firm went into administration in February.
