What did he do?
http://www.theguardian.com/media/2015/mar/25/jeremy-clarkson-top-gear-contract-bbc?CMP=fb_guHe got in a heated argument with one of the show's Producers at a hotel, apparently over a lack of a hot meal.
The argument then turned to a 30 second fight, where apparently the producer didn't retaliate.
Finally, Clarkson went on to shout and berate the producer infront of him and behind his back.
The producer was left bleeding and went to A&E.
This is on top of his previous public incidents.
He was asked to leave Argentina last year, after he had license plates which apparently referenced the Falklands War
And an out-take was leaked last year, where he mumbled the word "monday", but the take was re-done without the word.
And he made a comment the other year in the programme, where he claimed a bridge the team had built had a "slope on it", at the same time that an Asian person was walking along it. This was seen as tribal by some.
