NEW YORK — Fox News on Wednesday fired daytime news anchor Ed Henry after an investigation of sexual misconduct in the workplace.

The network said it had received a complaint last Thursday from an attorney about the misconduct. An outside investigator was hired and, based on the results of that probe, Fox fired Henry.

Fox offered no details of the complaint that resulted in Henry’s firing, only to say that it happened “years ago.” A lawyer for Henry, Catherine Foti, said he denied the allegations “and is confident that he will be vindicated after a full hearing in an appropriate forum.

Henry, who co-anchored “America’s Newsroom” between the hours of 9 a.m. and noon on weekdays, had slowly rehabilitated his career on Fox following a four-month leave of absence that ended in 2016. That followed published reports of Henry’s extramarital affair with a Las Vegas cocktail waitress.

Meanwhile, HarperCollins said Wednesday that it would no longer publish a book by Henry that had been scheduled for September. Titled “Saving Colleen: A Memoir of the Unbreakable Bond Between a Brother and Sister,” it was about Henry donating part of his liver to his sister.
