One of the biggest copyright piracy factories ever found in the UK has been discovered in Sussex.

Police seized 150,000 CDs and DVDs and 100 full computer hard drives at a flat in Bognor on Tuesday.

They said they found a 25,000-title catalogue of music, films and software, and eight pieces of equipment used to copy discs.

Two men were arrested on suspicion of conspiracy to contravene copyright laws and money-laundering.

The raids were carried out by the North West Regional Crime Unit, as well as investigators from the BPI (British Recorded Music Industry) Ltd – the trade body for the record industry.

The factory was found in a flat above a shop in High Street, Bognor, on Tuesday morning.

A 50-year-old man was arrested at the flat.

A 23-year-old man was arrested at a house in Broomcroft Road, Felpham.

Both men were released on bail without charge until June 5 next year.

David Wood, director of anti-piracy for the BPI, said, "I would like to thank both the Northwest Regional Organised Crime Unit and Sussex Police for co-ordinating their efforts to disrupt this prolific production of counterfeit music, film and game repertoire.

“These arrests are significant in that it is one of the largest 'domestic factories' uncovered to date in the UK.

“It had the capability of manufacturing and distributing counterfeit product on a truly commercial scale."

Detective Inspector Chris Neilson, of the Sussex Police economic crime unit, said: "Detectives and financial investigators from our unit are investigating, and are working closely with the BPI and North West England Regional Asset Recovery Team to fully investigate this 'factory'."
