From my log book:- There was some mystery over this a/c as it was supposed to have landed at Dubai A/P. Usually access to an aircraft was granted by the pilot or crew but they wouldn't allow me onboard this one........I wondered why? Later learned that it was impounded at Karachi A/P in August of the same year for allegedly being used in a "gun-running" operation! Apparently it lay derelict at the airport for many years until taken on by the Pakistan Air Force Museum to be refurbished and put on display.
