Five people have been arrested in a police raid on what is thought to be the largest DVD piracy factory discovered in the UK.
The Metropolitan Police's film piracy unit found more than 60 DVD copying machines and 30,000 blank discs in the search of the east London premises.
Officers said the factory in an industrial estate in Leyton was capable of producing 2,700 DVDs an hour.
A large number of printed cover inlays were also found.
Four men, aged between 21 and 36 years-old, and a 41-year-old woman were arrested.
The raid was a joint operation between the film piracy unit, trading standards and the Federation Against Copyright Theft (Fact).
Det Sup Trevor Shepherd said the operation underlined the value of police working in partnership with industry to tackle organised crime.
Fact director general Raymond Leinster said the operation was another "major intervention" against the distribution of counterfeit films in the UK.
