Strampel oversaw Nassar, the former MSU and USA Gymnastics doctor who pleaded guilty to abusing more than 200 young girls and women over more than two decades.
William Strampel, the ex-dean of MSU's College of Osteopathic Medicine, was being held in Ingham County Jail, but no charges have been filed. He's been charged with two counts of Willful Neglect of Duty; one count of fourth-degree Criminal Sexual Conduct; and one count of Common Law Offenses.
The Lansing State Journal reported investigators discovered pornography on Strampel's work computer and that he groped a female student.
William Strampel, who was dean of the College of Osteopathic Medicine until late a year ago, was charged Tuesday with a felony, a high court misdemeanor and two misdemeanors.
Strampel told police last spring his interactions with Nassar were minimal until a female student complained of Nassar inappropriately touching her in 2014.
Nassar is now serving his 60-year federal prison sentenced in United States Penitentiary Tucson in Tucson, Arizona, which is a maximum-security federal prison that offers a sex offender program for sex offenders such as Nassar. The most prominent of those cases featured a sentencing hearing in January in which dozens of women alleged misconduct by Nassar in two weeks of testimony.
Strampel announced a leave of absence for medical reasons in December previous year.
An attorney for Strampel, who has been on medical leave from the university since December, could not be reached by Reuters for comment on Monday evening.
A press conference is scheduled Tuesday afternoon with Special Prosecutor Bill Forsyth, who was appointed to investigate MSU's handling of the complaints. Among them, Nassar agreed to explain procedures to patients before touching them in sensitive areas, to always have someone else in the room when performing these procedures, and to either wear gloves or perform treatment over clothes, to minimize skin-to-skin contact.
Strampel was named the dean of the osteopathic medical school in 2002.
Though he resigned as dean, Dr. Strampel remains on the medical college faculty - an embarrassment that John Engler, interim MSU president, wants to end.
Back in October 2016, Strampel allegedly told a group of individuals that he did not believe that Nassar had actually committed any crimes of sexual abuse, stating how "patients lie to get doctors in trouble".
John C. Manly, attorney for Nassar's victims, released a statement following Stampel's arrest saying he was "encouraged" by the news.
