Ontario provincial police say they've charged seven men with credit and debit card fraud at the Fallsview Casino in Niagara Falls.

Police say the group used numerous ATM machines within the casino on Thursday afternoon.

Investigators say the group obtained significant quantities of cash from hundreds of compromised bank accounts over a two-hour period.

Casino enforcement unit officers arrested seven men and recovered more than $15,000 in cash and hundreds of credit cards.

Investigators believe the group was capable of defrauding Canadian banks and personal bank accounts of $250,000.

Seven men from Toronto, Mississauga, Cornwall and Markham are charged with possession of stolen property.

Police say more charges are pending.
