Michaels Inc, a popular art-and-craft store chain, is warning customers of a possible data breach similar to the one that plagued Target over the holidays. Michaels CEO Chuck Rubin says they are working closely with federal officials and are encouraging customers to closely monitor their bank accounts for unauthorized charges. Company officials are not saying when the data breach may have occurred. If you believe your card information was compromised, contact your bank or card issuer right away. Michaels has 22 stores in Minnesota, including in Mankato. For more information on the investigation go to www.michaels.com.
