During normal night-flying practice at 2230 hours on 16th Jan, one of British Mosquitos xxxxxxxx was vectored on to an unidentified A/C at 22,000 ft. A long chase ensued commencing over the North Sea about 50 miles from the Dutch Coast and ending at 2300 hours over Norfolk. Two brief AI contacts were made but faded quickly. The unidentified aircraft appeared to take efficient controlled evasive action.

No explanation of this incident has been forthcoming nor has it been repeated.
