Facebook has lost a copy of the personal details of more than 20,000 of its employees after hard drives containing unencrypted payroll information were stolen from an employee's car.

The antisocial network said it is in the process of informing those who were exposed, though so far there is no indication of the purloined details being used for fraud, it is claimed.
