Some car thieves picked the wrong Milwaukee Nun to rob...

FOX's Gary Baumgarten reports:

They may have thought the elderly Nun getting into her car outside Milwaukee's St. Joseph Convent would be an easy target...

After all, she's in her 70's, but they were wrong to think so, not only did she rush into the car and lock the doors, but cops say she chased them as they drove away!

(Sister Catherine) "So Sister shared with the police as much as she was able to identify about the vehicle and part of the license plate."

That's Sister Catherine Ryan, who says the Convent also has security cameras... What they captured was also turned over to the police.
