When £26m was stolen from the Northern Bank, the serial numbers of 150,000 £10 notes thought to be stolen were released in the hope that the robbers could be traced. That didn’t work.
So on this date, £240m worth of notes were re-issued in a different style and colour to make the old currency invalid. But still no one has been charged with the actual robbery.
The robbery had been carried out with military, some said paramilitary, precision but the IRA has always denied responsibility.
