Quebec City police say fake US $100 bills are still circulating around town despite an arrest last month.
Police say the fake bills have the inscription "Motion Picture Purposes" on them instead of "The United States of America" which appears on the real currency.
They say in a release that despite arresting one person last month, they believe other suspects are still circulating the bills.
The fake currency was first reported in town on Aug. 6.
Police are asking shopkeepers and shoppers to keep an eye out for the fake bills and call local police if they come across it.
