A major credit fraud ring has been broken up by Canadian police in Edmonton, Alberta, after a traffic stop of a car with stolen license plates, police said.

Detective Bob Gauthier announced the case at a news conference Monday, saying it opened June 28 when two rookie police officers spotted the car with stolen plates, the Edmonton Journal reported.

Inside the car, the officers found about 80 counterfeit credit cards and drivers licenses and a small amount of drugs, Gauthier said. The man and woman were arrested.

The discovery led to a search at a rented condominium, where officers discovered a mother lode of more than 1,000 credit cards in various stages of creation, a credit card imprinter, a counterfeit Canada Post key and stolen computer equipment, the report said.

"We have evidence from break-ins, from frauds, there's drug entanglement here, there's theft of mail, stolen checks, counterfeit checks, stolen identification, counterfeit identification," Gauthier said. "This is an absolutely huge seizure; certainly the biggest I've seen."

The condo search also resulted in the arrest of another man and woman, and Gauthier said more arrests are possible as the investigation has extended into other provinces, the report said.
