The popular craft-store, Michaels, says computer hackers, might have stolen information from customers.
Michaels' officials aren't saying much about the possible breach, but they're telling their customers to check their accounts for any fraud or theft.
If it is confirmed, it would be the second time recently that Michael's has been hit by hackers.
Michaels has three stores in Tulsa.
They got hacked back in 2011.
