A former Michigan State University dean who oversaw USA Gymnastics abuser Larry Nassar has himself been arrested for alleged criminal sexual misconduct.
William Strampel, 70, is accused of inappropriate sexual conduct and of storing nude photos of students, report local media.
He was fired this year for not enforcing protocols to keep check on Nassar after a victim came forward.
Nassar is in prison for sexually assaulting hundreds of girls.
Police said Mr Strampel was arrested on Monday and would be formally charged in court on Tuesday afternoon.
He was dean of Michigan State University’s (MSU) College of Osteopathic Medicine from 2002-17.
Mr Strampel stepped down at the end of last year ostensibly for medical reasons, but initially remained on the college’s payroll.
Local media report that pornographic images were found on his work computer, and four female victims accused him of sexual harassment.
The university has faced severe condemnation and public scrutiny for employing Nassar, 54, for years.
Nassar was a faculty member and worked as a physician at a clinic on the school’s campus, where much of the abuse took place.
According to Michigan Live, court documents say Mr Strampel, who supervised Nassar, grabbed the buttocks of two female students.
He also reportedly stored on his work computer a pornographic video, nude photos of women, and a clip of Nassar performing a “treatment” on a younger patient.
Mr Strampel solicited pornographic images of women who appear to have been MSU students, according to Michigan Live.
In February, MSU fired Mr Strampel for failing to enact strict protocols on Nassar when survivor Amanda Thomashow accused Nassar of abuse, according to the Detroit Free Press.
“William Strampel did not act with the level of professionalism we expect from individuals who hold senior leadership positions, particularly in a position that involves student and patient safety,” said university interim president John Engler in a statement.
After Ms Thomashow’s complaint against Nassar in 2014, Mr Strampel allegedly restored the doctor’s position at the school, during which time he was able to molest 20 more women before coming to trial.
Every member of the USA Gymnastics board quit following Nassar’s widely publicised trial where hundreds of women came forward with personal testimonies about his abuse.
A lawyer representing more than 150 Nassar survivors praised the Michigan attorney general for the arrest of Mr Strampel.
“Our clients are encouraged by the Attorney General’s action today,” attorney John Manly said in a statement, according to the Detroit Free Press.
“It demonstrates that he is serious about investigating the systemic misconduct at MSU that led to the largest child sex abuse scandal in history and holding the responsible parties accountable.”
