ANN ARBOR, Mich. -

The University of Michigan Union Ticket Office supposedly was hacked recently.

Anyone who purchased tickets at the office within the past two years may have had their personal information compromised. A breach in the system database was detected at the end of April.

It's believed the hack happened back in September 2011. Reports show 33,000 people may be affected.

Anyone who bought tickets at the office is urged to check bank statements.
