For the first time, Baylor University has revealed details of how it says former football coach Art Briles and others in the school's athletic department handled allegations of a 2012 gang rape involving five players.

According to the information released by Baylor on Friday, the student-athlete told her head coach in April 2013 that five Baylor football players had sexually assaulted her a year earlier. She provided the players' names.

The coach then reported the assault and the football players' names to his sports administrator Thomas Hill, Briles and athletic director Ian McCaw.

None of them, including the woman's coach, passed along the allegation to the university's Judicial Affairs office, as required by federal Title IX rules, according to officials. Baylor said Friday that Briles and McCaw have told the university they did not report the allegations to Judicial Affairs.

Briles could not be reached for comment Friday, but his attorney challenged Baylor's account.

"As usual everything Baylor is saying is false," Ernest Cannon said, adding, "They're up to the same underhanded and dirty tricks."

McCaw could not be immediately reached for comment Friday night.

Hill, who was fired after an investigation by the university's board of regents, also could not be reached. Hill's attorney, Rogge Dunn, spoke on his behalf and said that Hill was notified of the alleged incident by the alleged victim's head coach and was told it had already been reported to McCaw.

Dunn said the coach, "did not expect, nor did he request Hill take any action," but that Hill reported it to his immediate supervisor anyway and "was told that he need not take any further action as the matter was being handled by Baylor."

In an affidavit obtained by Dunn, the alleged victim's coach confirms Dunn's account and said that he had told Hill of the incident and had "followed proper procedures" by reporting the incident to McCaw.

For two years, Baylor has struggled with a sexual assault scandal that came to light as a result of incidents involving the football program. Regents told The Wall Street Journal that 17 women had reported domestic violence or sexual assaults that involved 19 players since 2011, including four gang rapes. Later, regents told The Dallas Morning News that the school is reviewing about 125 cases of sexual assault or harassment involving women campus-wide.

The investigation ​led to ​Briles' firing, the resignation of McCaw and the demotion of school president Kenneth Starr, who later resigned.

The new details from the university come after Kendal Briles — Baylor's football offensive coordinator and Briles' son — and other coaches and staff members issued a written statement that the female athlete's head coach who notified Briles had said he'd reported the assault to Judicial Affairs himself.

But Baylor officials said records and interviews with Judicial Affairs employees confirm that no one reported the rape allegations in 2013.

Baylor officials also said that when the school's Title IX office learned of the rape allegations in 2015, McCaw denied he had known about them.

"The internal system of discipline operated by the coach was not in line with the University's mission and obligations," Ron Murff, board of regents chairman, said Friday evening. "To Art's credit, he took responsibility for this in discussions with the Board of Regents and in a national media interview."

Baylor's Office of General Counsel is examining sexual assault cases to determine how they were handled.

The NCAA has said it won't impose "sweeping sanctions against the school for broad institutional failings," The Wall Street Journal reported Tuesday. Instead, the program faces a more narrow NCAA investigation.

Baylor's release of details about how coaches handled the report of the gang rape comes one day after ​b​illionaire Drayton McLane, former Gov. Mark White, former football coach Grant Teaff and other influential alumni and donors demand​ed​ more transparency from school regents.

They said regents must release the full investigation into how the school handled sexual assaults.

​Bears for Leadership Reform demanded Thursday that Baylor regents also conduct open meetings, publish agendas and minutes, and discuss decisions publicly. And the group wants Baylor to disclose what the university has spent on settlements and legal fees for pending lawsuits. The group also wants a voice in selecting a new president.

The controversy has divided students, alumni and fans. ​​​In addition to Kendal Briles and other assistant coaches' shows of support for Art Briles, ​fans lined up to buy black T-shirts with the former coach's initials before Baylor's home game against TCU last week​.​ ​A​ similar banner hung from a stadium luxury suite.
