(AP) — A Las Vegas company that owns casinos in four states, including one in St Joe, says a data breach has compromised customer credit and debit card information.

Affinity Gaming says its system was infected with malware that compromised card data from customers at its 11 casinos, including five in Nevada, three in Colorado, two in Missouri and one in Iowa.

Affinity owns the St Jo Frontier Casino.

The company recommends that customers who visited the casinos between March 14 and Oct. 16 check their card statements for suspicious activity and put a fraud alert on their accounts.
