Guests of the Radisson Hotel should check their credit card statements carefully after a security breach of the company's computer systems.
Hotels in Canada and in the United States are said to be affected after computer systems which stored guests names and info, like credit card numbers; were illegally accessed from November 2008 to May 2009.
The company says it can not confirm which hotels specifically are affected, but the company does say social insurance numbers were not stored in the database.
The Radisson first learned of the breach by the credit card companies used by the hotels, such as Visa and Mastercard.
