LONDON — An off-set altercation has imperiled the internationally known TV car show “Top Gear,” one of the BBC’s most lucrative productions.

BBC News said Wednesday the broadcaster has postponed the three remaining episodes after suspending host Jeremy Clarkson over a reported “fracas” with a producer. The BBC hasn’t given details about the incident, but co-host James May characterized it as “a bit of a dustup.”

“But I don’t think it’s that serious,” he added.

The blend of car news, humor and blokey banter in “Top Gear” has won it legions of fans. The current series was launched simultaneously in more than 50 countries and the BBC has sold the format for locally produced versions in the U.S., China, Russia, Australia and South Korea.

It has also attracted controversy, much of it attached to 54-year-old Clarkson, one of three presenters and a self-styled enemy of “political correctness.”

In October, the “Top Gear” crew was forced to flee Argentina after facing violent protests for allegedly referencing the 1982 Falkland Islands war on a license plate.

Clarkson also asked for forgiveness last year after allegedly using the racist n-word during filming for the show. He said then had been given a “final warning” by producers.

In 2011, the BBC apologized to Mexico after Clarkson and his co-hosts characterized Mexicans as lazy and oafish.

Prime Minister David Cameron called Clarkson a friend and a “huge talent,” and said his children would be “heartbroken if ‘Top Gear’ is taken off air.”
