Police blitzed an industrial estate in Campbellfield last night in a crackdown against hoon drivers, checking out 200 cars.

Twenty two cars were impounded and 80 notices of unroadworthiness were issued during the blitz at an industrial estate that is notorious for illegal drag-racing.

Up to 300 onlookers who gathered to watch the event were each hit with $200 fines from Hume Council, police said, while the Sheriff's Office recovered about $115,000 in outstanding fines.

The Environment Protection Authority (EPA) also handed out 33 notices for noise pollution offences.
