The $889 million Los Angeles Firemen's Credit Union has notified some of its more than 28,000 members that private information may have been compromised.

The May 10 letter from CEO Michael Maestro said that "an extremely small percentage" of member files were "not properly moved" when the CU relocated from an old location. The data that could have been compromised included members names, addresses, phone numbers, account numbers, social security numbers and other identifiers.

The CU sought to reassure members that it did not believe any of their information had been compromised and that the CU had "state of the art protocols" available to validate member identifies. The CU also arranged for CU members who chose to do so to be able to enroll in a credit monitoring service for the next two years at no cost to them.
