The BPI's efforts to bring down Robert Langley, one of Europe's most notorious bootleggers, were rewarded Friday (July 27) when he pleaded guilty to copyright and trademark infringement charges in court.

Langley, also known as "Mr Toad," was originally arrested in February 2005 following a raid at a Scottish record-music fair in a joint exercise with BPI anti-piracy officials, Scotland's Strathclyde Police and Glasgow-based Procurator Fiscal Service.

Described by the BPI as the U.K.'s "biggest player in bootlegging", Langley operated two labels, Silver Rarities and Langley Masters, that sold illegal recordings of live concerts for £6-£300 ($12-$607) each.

"He'd amassed a huge personal fortune by ripping off musicians, record labels, music publishers and the state, but justice has finally caught up with him," said David Wood, BPI's anti-piracy manager, in a statement.

After today's conviction, Langley must return to the Glasgow Sheriff Court on Aug. 30 to be sentenced. According to a BPI spokesperson, Langley faces up to 10 years in prison.

On Sept. 20, the prosecution team will claim about £250,000 ($506,000) of his assets at the same Sheriff Court under the 2002 Proceeds of Crime Act.
