R-C-M-P have issued a warning about what they describe as an "emerging" fraud scheme targeting a cluster of businesses in Richmond.
A police statement says the businesses have lost tens of thousands of dollars.
The Mounties say the fraudsters appear to be intercepting and cashing cheques from the businesses that are being mailed using a nearby Canada Post mailbox.
They say police are working with Canada Post security personnel as part of the investigation, and they're encouraging people to use post offices or a courier service rather than mailboxes for sending corporate cheques.
