The RAF has some more history on a similar theme.
In the early 1980s at Gutersloh an RAFP NCO was convicted of "liberating" a sub imprest from a pilot's locker in the main hangar in the middle of the night (no excuses for it being there). Most worryingly, it was hidden in a pile of used underwear.. Why the hell would he be looking there..?
Also, Odiham's OC Catering went AWOL in the mid 80's. He was found living rough on Salisbury Plain, IIRC. He'd supposedly lost his memory, poor chap (along with a whole bunch of mess funds).
