Dashcam footage has emerged from the UK of a group of extremely reckless "boy racers" being dealt swift justice for their dangerous driving.

The video shows several motorists weaving dangerously at high speed between cars on a road in Southport on June 1.

Further down the road, one of the vehicles can be seen pulled over to the side of the road by police.

"Yes! Well done!" the filmer can be heard exclaiming.
