Top Gear host Jeremy Clarkson has been suspended by the BBC "following a fracas" with a producer.
The corporation said the 54-year-old presenter had been suspended "pending an investigation".
"No one else has been suspended. Top Gear will not be broadcast this Sunday," it said.
Clarkson was given what he called his "final warning" last May after claims he used a racist word while filming the popular BBC motoring show.
At the time, he said the BBC had told him he would be sacked if he made "one more offensive remark, anywhere, at any time".
The BBC gave no further details on the current incident involving Clarkson, and said it would not be making any further statements at this time.
Clarkson's representatives have yet to reply to requests for a comment.
The presenter himself has remained silent, however last month he tweeted a post saying a "new presenter for Top Gear" was wanted.
"Applicant should be old, badly dressed and pedantic but capable of getting to work on time," he said.
Former Top Gear presenter Chris Goffey told BBC Radio 5 live while discussions on the programme sometimes became heated when he worked on the show, "it must have been something fairly serious behind the scenes to warrant his immediate suspension.
"I can't think what the hell's gone on, but there you go. When you've got a very strong character who likes things his own way, if somebody stands up to him, there's going to be a row."
TV critic Toby Earle told the BBC he was not surprised at Clarkson's suspension. "This incident is the one that's really forced management to take action," he said.
"Part of the show's appeal, to many viewers, has been it's sort of edginess and the fact that it's rough around the edges - in some ways takes no prisoners.
"But of course there is a very delicate line to tread with that, and it has crossed that line I feel."
But the TV Times' Mary Evans said she did not think it was the end of the road for the presenter: "He is what he is, like him or loathe him.
"He knows who he is and he knows what he wants to say. Top Gear obviously existed before him, and it wasn't the phenomenon that it is now. So obviously it has something to do with his personal charisma and his fanbase.
"I can't see this will be it for Clarkson, I really can't. But I think he's probably slightly overdue a slap on the wrist," she told the BBC.
