"We realize this is a major inconvenience and cause for real concern, and we deeply apologize to everyone affected by this incident," Cagen said. "Even though we have no indication that the thief has accessed the data, we are doing all we can to help our patients and employees protect their information."

The incident is the second data theft from a motor vehicle announced this week. on Thursday, Minneapolis-based financial services company Ameriprise Financial Inc. said it is notifying some 158,000 customers and 68,000 financial advisers that a laptop containing personal information about them -- including names, account numbers or Social Security numbers -- was stolen from a parked car late last month.
