A Jamisontown industrial unit has allegedly been used to manufacture pirated DVDs, according to Penrith police.
Officers attended the Abel Street address on October 4 in relation to investigations into possible copyright offences and the manufacture of pirated DVDs, a Penrith police spokesman said.
DVDs were allegedly being manufactured at the time and police made arrangements with the Australian Screen Association to attend the location, where a search warrant was executed.
Police seized a large amount of property, including computers and Eftpos machines, the spokesman said.
Further inquiries are being conducted by the Penrith Proactive Crime Team and further action is expected in relation to copyright offences.
No charges have been laid in relation to the offence.
