From the BBC:
Top Gear host Jeremy Clarkson initiated the BBC investigation which prompted his suspension, after he informed BBC bosses of the alleged "catering foul up".
BBC News understands that the star phoned BBC head of television, Danny Cohen, to report the lack of hot food. Producer Oisin Tymon, with whom the altercation took place, is not believed to have filed his own written report.
Interviews are expected to be held with the star and other parties next week, and the show has been taken off-air. Clarkson has expressed dissatisfaction with the catering, which his co-presenter James May labelled "a bit of a fuck-up".
