Edmonton police are warning the public about a flood fundraising scam.
Sergeant Mike Walkom says the department alleges that a week ago, a young blonde woman set up a booth at a city shopping mall and sold boxes of Krispy Kreme donuts, telling people the proceeds would go to flood victims in Calgary.
Sgt. Walkom says the woman wouldn't take cash, just credit and debit cards, but police allege the information from those cards was then compromised.
Sgt. Walkom says the total of fraudulent charges is in the thousands of dollars and expected to grow.
Any other possible victims are urged to contact police.
