A man and three women have been arrested after bootleg DVDs and CDs thought to be worth £5m were recovered by police in Glasgow.
The unreleased film Shrek 2 was one of the DVDs being bootlegged
The films seized included titles such as the latest version of Around the World in 80 Days and Shrek 2, which are not yet on general release.
Copying equipment and cash were taken from three premises in the city centre and the east end.
The operation was described as a "major success" by industry body, Fact.
A city-centre shop, a factory in the east end and a house in the east end were targeted in the swoop.
Machinery capable of churning out about 250 copied CDs and DVDs an hour was found as well as a haul of cash.
A man and three women were in police custody in connection with the recoveries
while further inquiries were being carried out.
John McGowan, senior investigator for Fact (Federation Against Copyright Theft), said: "This is the biggest recovery for years, certainly one of Scotland's
"We got the manufacturing facility which was banks of copiers - basically an
illicit factory which has been set up with banks of copiers which copy films or
music discs. They could copy 60 films in 15 minutes.
"This would inflict tremendous harm not only on the film
industry but also on
local retail and rental outlets and the music industry."
Mr McGowan said the goods would have been sold at markets, on the internet or through factories.
He said those involved had stood to make a "tremendous profit" with discs
costing between 30p and 80p to copy yet being sold for around £5 each.
Mr McGowan said one of the premises was on railway property and that the transport
police had been used to carry out the search.
