ANN ARBOR, Mich. – Michigan State Police are investigating a former employee of the $334 million University of Michigan Credit Union after it appeared that the employee may have stolen some records from the CU that were subsequently used for identity theft. James Mattson, CEO of the credit union, said the employee was let go after CUNA Mutual ended her bond coverage. The employee was responsible for logging in member records that were held in a storage facility before they were handed over to a contractor for destruction. The CU sent letters to 5,000 of its 44,000 members warning them of the possible fraud and has offered them free fraud protection and monitoring. Mattson said the number of members contacted was so high because the CU discovered a box of records could not be accounted for and the CU wanted to make sure all members whose records may have been compromised were notified. The fraud came to light when a CU member received a call from Dell asking about the address to which she wanted to have a computer the company said she ordered shipped. The member had not ordered any computer and contacted the police.
