Rupert Murdoch’s media company has been struggling for nearly a year to contain a sexual harassment scandal that has engulfed its Fox News unit in New York. Now, fresh allegations of a boorish workplace culture are dogging yet another unit — this time in Los Angeles — as Fox Sports announced that it had abruptly fired its controversial head of sports programming.

Jamie Horowitz’s dismissal Monday came about a week after Fox began investigating allegations of sexual harassment in the workplace in its sports division. The company interviewed several women at L.A.-based Fox Sports about Horowitz’s behavior, according to a person familiar with the investigation who was not authorized to publicly discuss it.
