Wellington police smashed their way into a car to arrest at least one person wearing a Mongrel Mob vest on a busy Porirua road.
The action was all caught on video by a member of the public and posted on the Wellington Live Facebook page this morning.
The video shows two patrol cars blocking a silver Subaru station wagon in the middle of the road.
An officer then repeatedly bangs on the driver's door window of a car until it smashes.
He can then be seen running around to the passenger's side of the car, out of view. However, it appears they are struggling with someone on the ground.
