A woman has admitted manufacturing and selling thousands of fake DVDs and CDs after being secretly filmed at the famous Barras market in Glasgow.

Audrey Bisland produced the counterfeit discs using sophisticated equipment at a flat nearby the infamous market before selling them on at her popular stall. She was secretly filmed selling the goods by agents from the Federation Against Copyright Theft (FACT) on several occasions before police were called in to search various properties.

The officers discovered that a flat on Tobago Street, Glasgow, had been turned into a "factory" which produced thousands of dodgy discs to supply the market stall.

At Glasgow Sheriff Court on Thursday, 30-year-old Bisland from the city’s Drumoyne admitted making and selling the fake goods which breached copyright laws at a flat in Tobago Place, Glasgow, and the Kent Street market between October 2007 and August 2008.

Her accomplice, Maria O'Neill, 57, of Belvidere Gate, Glasgow, also pled guilty to selling the discs after she was also filmed working at the market stall on various dates between October 2007 and August 2008. Prosecutor Derek Buchanan told the court that FACT officers often monitor counterfeit hot spots such as The Barras to identify illegal traders.

Mr Buchanan said: "The accused Audrey Bisland came to the attention of the authorities as a person who was operating a stall at Kent Street. It was clear to FACT that she was running the stall on a Saturday and Sunday and so they arranged for test purchases to be made.

"They used a button-hole camera which enabled them to film the activities of the accused and Maria O'Neill who was also involved in selling from the stall.

"Observations were also made by FACT that there were comings and goings from a flat at Tobago Street which belonged to a relative of Audrey Bisland and this information was passed on to police who thereafter obtained a search warrant.

"The flat was searched on August 23, 2008, and police effectively found a factory for the production of counterfeit film and music discs. There were six multi-burners within the bedroom and each had six drawers which would allow for considerable copying.

"A shopping trolley was also found which contained in excess of 2,000 counterfeit discs."

The court heard that Bisland's and O'Neill's homes were also searched and officers found large quantities of discs at both addresses. O'Neill was arrested and Bisland - who was on holiday at the time of the search - was arrested when she returned home a few days later.

Mr Buchanan added: "The stall which was being run by Audrey Bisland sold various counterfeit film and music items ranging in price from £5 to £15. £5 was the normal price for most items but there were MP3 recordings commonly know as typhoons which contained up to 60 albums and these sold for £15.

"There were various helpers involved in selling the items and also watchers who stood in nearby lanes who acted as lookouts for the police. It was clear to FACT that it was a thriving enterprise which was popular with customers at The Barras market."

Sheriff Charles McFarlane QC deferred sentence until next month for background reports and both women were released on bail.
