The banking details of up to 11,000 University of Victoria staff members were stolen over the weekend and the administration is warning they could be up against identity fraud.

Saanich police are investigating how the thieves were able to break into the university administration building Saturday night and steal a safe and electronic devices containing the personal information.

Thousands of employees' payroll details, such as direct deposit banking and social insurance numbers, were among the stolen information.

The university is advising its staff to alert financial institutions and credit card companies which may need staff to close current bank accounts.

However, the university has said there has been no evidence that the information has been accessed or misused.

The privacy's commissioner office was notified of the theft and the university said it will begin a review of the system's information security processes.
