Police have confirmed they are now investigating an incident in Christchurch on Saturday night that led to a viral Facebook video.
A van was caught on video braking so hard the van nearly tipped upside down.
The incident happened on Deans Ave, in Christchurch, on Saturday night.
A Christchurch resident who asked not to be named uploaded the video of the dangerous driving to his Facebook page shortly after filming it.
"Jesus Christ," he wrote in the caption.
