Strange Black Gazelle??

Seen landing at Farnborough airport this week near special projects was a black Gazelle, no serial number could be seen although this may have been in small print or even subdued, this aircraft was fitted with stub wings as used on Northern Ireland versions and still strange further this carried a FLIR pod and TIALD pod. Appropriate phone calls were made but Boscombe Down/Warton/Westland denied any knowledge this leaves this as a possible goverment agency MI5/6 etc.

Replies and other sightings most welcome.
