Four women who worked at a U.S. spy agency alleged that former Indiana University men's basketball coach Bob Knight groped or touched them inappropriately before and after a 2015 speech he gave to their agency outside Washington, D.C., according to The Washington Post.

Citing investigative documents and interviews with people in the spy agency, The Post said the accusations arose from Knight's visit to the National Geospatial-Intelligence Agency, which does mapping and provides satellite imagery for military planners.

From the Washington Post:

"The women accused Knight of a range of boorish behavior: from touching them on the shoulder while commenting on the attractiveness of their legs, to hugging them too tightly around the chest, to hitting them on the buttocks, according to documents compiled by investigators and Washington Post interviews with three of the women."

The accusations prompted an investigation which lasted a year and prompted notifications to Congress, the Pentagon and other intelligence agencies. That inquiry concluded after Knight denied the behavior during an interview with the FBI at his home in Montana, The Post reported. Federal prosecutors in Virginia, where the spy agency is located, declined to bring charges.

Knight's attorney in Indiana, Jimmy Voyles, said investigators from both the FBI and the United States Army were involved and that neither could substantiate the allegations.

"All I can tell you is there was absolutely no credible evidence that supports any of the allegations and two of our finest investigative agencies — the Army and the FBI — made those independent determinations," Voyles told IndyStar.

Knight first learned of the accusations a year after the event, according to Voyles, when he got a call from the FBI. Voyles said he responded on Knight's behalf. He declined to discuss the FBI's visit to Montana.

A broadcaster who was once a legendary college basketball coach, Knight was known for his fiery courtside temper and sometimes profane language and stories. There were objections to Knight's appearance at the spy agency, The Post reports, well before the event took place.

But Knight had key connections to the spy agency.

As a young basketball coach at West Point, Knight befriended Richard Cardillo, a young Army captain, and he allowed Cardillo's son Robert to serve as a ballboy, The Post reported. Knight maintained a friendship with the family ever after.

Robert Cardillo, now the head of the spy agency, invited Knight to speak there, Voyles said. And Richard Cardillo accompanied Knight for the evening. The allegations following Knight's appearance — and the aftermath — have roiled the spy agency, The Post reported.

Efforts by IndyStar to reach Knight on Friday were unsuccessful.

The Post reported that his wife, Karen, responded to the paper's inquiries with a text, saying: "Bob did nothing wrong and there is NO evidence to prove that he did. Case closed."

Voyles said simply: "Mr. Knight denies any kind of wrongdoing whatsoever, and there was no credible evidence to support any of it."

Knight's next scheduled public appearance in Indiana is July 15 at the Indiana Grand Racing & Casino, where he is scheduled to mingle with guests and hold an autograph session around the Indiana Derby. A spokesperson for Centaur Gaming Properties, which owns the casino, declined comment.
