A man was arrested after police found what they called a “breakdown department” on an industrial estate in Norfolk.

Officers were alerted on Thursday to suspicious activity inside a unit at Snetterton Business Park on Harling Road, near Attleborough.

They found four cars and several spare parts believed to be stolen.

Police said a man in his 20s was arrested in Norwich on Friday on suspicion of robbery, handling stolen goods and possession of Class B or Class C drugs.

He was released on bail until January.

A police spokesperson said: “It is believed the premises were being used as a ‘dismantling shop’, where vehicles are illegally dismantled or ‘cut up’ for parts and sold for profit.

“Officers have spent five days dismantling the site and inquiries are now underway to ensure the safe return of the vehicles, which were stolen in London, to their owners.”
