Dr. William Strampel, the former boss of Larry Nassar at Michigan State University, has been arrested.

Strampel, 70, is listed as an inmate in Ingham County jail, according to an inmate search on the county's website. No charges are listed. MSU spokeswoman Emily Gerkin Guerrant confirmed Strampel had been arrested, but could provide no other details. Michigan State Police directed calls to the attorney general's office, where a spokesperson did not confirm the arrest.

Strampel, the former dean of the MSU's College of Osteopathic Medicine, is facing revocation of his tenure by interim MSU President John Engler, the first step in terminating his employment. The move is in response to Strampel's failure to monitor and enforce clinical practice guidelines put in place for Nassar following a 2014 sexual harassment investigation.

His arrest comes the day before a press conference from Bill Forsyth, an investigator hired by Michigan's Attorney General Bill Schuette to investigate MSU's handling of the Nassar scandal.

Nassar, a prominent sports medicine doctor at the university, is in prison for possession of child pornography charges and was sentenced on charges that he sexually assaulted multiple women, often under the guise of medical treatment. More than 150 women and girls, including Olympic gymnasts, spoke at Nassar's sentencing hearings in Ingham and Eaton counties, saying he sexually assaulted them - the vast majority patients.

Many said they had told coaches, trainers and even police about the assaults, but nothing was done.

It was Strampel who, after a 2014 Title IX complaint and police report lodged by Amanda Thomashow, sent an email putting Nassar back to work with a series of conditions, including having another person in the room when he was performing procedures in sensitive areas and using gloves.

According to statements from Nassar's more direct supervisors in a March 2017 police report, Strampel did not make Nassar's colleagues aware of the conditions.

After Strampel put Nassar back in place, 20 more women say they were molested by him.

In all the university employed Nassar for almost two years while he was under investigation by other authorities.
