SACRAMENTO, Calif. (AP) – California’s Department of Motor Vehicles says it improperly disclosed private information to seven other government agencies on more than 3,000 people involved in investigations as suspects or witnesses.

The department is sending letters Tuesday to the 3,200 people after determining that they aren’t currently being investigated.

Department officials say they improperly gave federal, state and county agencies what were supposed to be internal notes, such as whether drivers’ Social Security numbers had been checked to see if they were valid or if the individual was ineligible for a Social Security number.

Information on more than 3,000 of the individuals went to district attorneys in just two of California’s 58 counties, San Diego and Santa Clara.

Information on fewer than 200 people went to the federal Department of Homeland Security.
