A Quebec man is facing charges in the wake of an automated banking machine skimming fraud uncovered Sunday in Saskatoon.

Police reported Tuesday that they were tipped off by staff at the airport-area Heritage Inn hotel, who discovered an unusual amount of cash in a guest room.

Saskatoon police said they checked it out and found about $100,000 in the room, in $20 bills.

Police said Tuesday that as many as 600 debit cards may have been compromised in the scam, which they believed began on Saturday and continued into Sunday.

'You very seldom hear about people entering the credit union or a banking institution and putting dynamite on the vault door. But this is the equivalent in the 21st century.'—George Keter, CEO Affinity Credit Union

In the weekend scam, a retail store was used to read and collect data from debit cards.

"These are the equivalent of 21st century bank robbers," said George Keter, CEO of the Affinity Credit Union, which reported that hundreds of its debit cards were compromised. "You very seldom hear about people entering the credit union or a banking institution and putting dynamite on the vault door. But this is the equivalent in the 21st century."

Keter said all affected customers were being contacted and would be reimbursed.

Police said that Diego Aparicio-Arguedas, 21, is charged with possession of the proceeds of crime.

He was arrested at the Saskatoon hotel where police found the money.

They said their investigation continues and that the accused man may have had accomplices.
