Larry Williams Drive

A grievous assault involving dirt-bike riders in East Auckland has prompted a warning from the local board and police.  Footage circulating online shows a motorist being cut off and swarmed at the intersection of Pakuranga and Fortunes Roads - and getting attacked as he tried to get away. Howick Local Board Chair Bruce Kendall says this is a symptom of an international phenomenon of people being reckless. "They end up in a bit of a mob mentality and they end up doing some pretty bad things. And I don't know how this situation got to this particular point - I've only seen the video from the point that the car is stopped...and it looks pretty dangerous to me."  LISTEN ABOVESee omnystudio.com/listener for privacy information.
