The Nelson and Brierfield Community Policing teams executed two fraud warrants with trading standards officers on Saturday.
The warrants were executed simultaneously at two shops in Leeds Road and Manchester Road, Nelson, and a quantity of suspected counterfeit DVDs and recording equipment was seized.
Both the shop owners are now assisting the police and Trading Standards with their inquiries.
Information from the community had been passed to local community beat managers regarding two commercial premises allegedly selling counterfeit DVDs. PC Tony Feather and PC Hazel Richardson attended the warrants with two teams from trading standards.
PC Feather said the operation was very successful, and the partnership between the police and trading standards had had the desired effect of targeting persons engaged in commercial counterfeiting in the Nelson area.
He said: “This should serve as a warning to anyone else engaged in this type of activity who sometimes see it as a victimless crime. However, the money made from counterfeit goods can often go to organised crime groups, or even help to fund terrorism.”
