A DUP councillor has claimed that a simple payslip error may have compromised the security of thousands of current and former PSNI/RUC employees.
The PSNI confirmed the error, which occurred last month, identified people receiving pay from the PSNI in payslips sent to banks and building societies.
The error was revealed by DUP councillor Jimmy Spratt who demanded an "immediate" investigation by North Secretary Mr Peter Hain and by the Policing Board.
Mr Spratt said: "Thousands of serving officers, including part-time reservists, civilian workers and retired people have their salaries paid into banks and building societies through a computer system.
"We could be talking about thousands of people having had their security breached and being forced to move house.
"This is another major embarrassment for the PSNI considering there is still a terrorist threat out there and considering one of the banks was breached last year in a major bank robbery," he said.
