The University of Michigan investigated allegations of sexual abuse against a former member of its physicians team, according to a recent report from The Detroit News.

The Detroit News reported that Robert E. Anderson, who is now deceased, was the doctor implicated in the reports. The University of Michigan said it investigated several “disturbing and very serious” allegations against the physician. Anderson was the the former director of University Health Service at Michigan.

University of Michigan police concluded the investigation in April 2019.

Anderson also was the top physician for Michigan football while head coaches Bo Schembechler and Lloyd Carr were in Ann Arbor.

School officials were first notified of the allegations in summer 2018, when a former student-athlete wrote a letter to University of Michigan Athletic Director Warde Manuel to explain the abuse suffered back in the 1970s.

“The allegations that were reported are disturbing and very serious,” University of Michigan President Mark Schlissel said in a statement. “We promptly began a police investigation and cooperated fully with the prosecutor’s office.”

The alleged sexual abuse and unnecessary/unwarranted medical examinations may have spanned from the 1970s through the 1990s, according to the report.

Anderson died in 2008.
