Recently-released movies and computer games were then sold on via an internet auction site as "genuine goods" and with prices slightly lower than shops.

Computers capable of copying 17 discs at a time and high quality printing equipment for artwork were also seized.

The haul included film titles such as Kill Bill 1 and 2 and the Doom 3 game.

Council trading standards officers accompanied by Avon and Somerset police and an investigator from the Entertainment & Leisure Software Publishers Association mounted the raid following a tip-off from a member of public.

An office was discovered in one of the bedrooms where internet orders were received and processed. Officers say hundreds of items of stock, master discs and orders ready to be sent out to customers were also seized.

A Tradings Standards spokeman said most of the business was being conducted over the internet:

"Unusually, customers were actually being deceived in this particular case as the discs being offered were described as new," he said.
