The interviewer, who thrilled the world with indepth specials about Princess Diana and Michael Jackson, was in the middle of a tense chat with Tommy Davis, the head of the Church of Scientology’s Celebrity Centre, when his guest removed his microphone and stormed out.
The interview, taped for Friday night's (23Oct09) Nightline programme in America, turned volatile when Bashir quizzed Davis about the church's involvement in the autism treatments of celebrity Scientologist John Travolta's late son Jett.
Bashir asked, "Do you know if the church ever advised them not to allow their son to receive certain medications."
Davis replied, "The church never advised them in any way, shape or form whatsoever on any aspect of their son's treatment. Never have, never will."
And when Bashir asked Davis if it was true that Scientology founder L. Ron Hubbard believed in an inter-galactic emperor called Xenu, the church spokesman refused to even dignify the question with a response. He stood up, calmly removed his microphone and walked off set.
