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.
