Although the 'official' date of first Police operation was 15 May 1985, I distinctly remember one operating in the Aldershot area using a police callsign the day before and when the tragic news came in the next day, thinking 'those may have been the guys I talked to yesterday'. When they departed from Aldershot, they had thanked us and told us it was a successful operation as they had traced the person they were looking for.
