Shocking footage shared online shows 300 youths at an illegal rave in an abandoned warehouse in Harrow in north-west London.
In the video, three youths are seen jumping on top of a police car outside the property on Waverley Industrial Park.
Others are seen leaping over fences and running away from police.
Another video clip shows police breaking down the doors of the warehouse, which were barricaded with plastic crowd control barriers.
Loud music can also be heard blaring from speakers, which were later seized by the police.
Captions on the video said the Met arrived with sniffer dogs and were able to disperse the crowd by 2:30am on Sunday.
A spokesperson for the Met told the Standard: “Police were called at around 23:30hrs on Saturday, 2 May to reports of an illegal rave at a disused warehouse in Hailsham Drive, Harrow
“Officers attended and moved on an estimated 300 people. Officers made three arrests, including two men on suspicion of organising the event and a third who was arrested on suspicion of organising the event and a third who was arrested on suspicion of being drunk and disorderly. A number of large speakers were also seized by police.”
