A signage at a Michaels arts and crafts store is seen in the Loma Portal area of San Diego, California January 27, 2014. Michaels Companies Inc, the biggest U.S. arts and crafts retailer, said it is investigating a possible security breach on its payment card network and advised customers to check their financial statements for fraudulent activity. If confirmed, it would mark the second known data breach since 2011 at Michaels, which is preparing to sell shares in an initial public offering.
