University of Michigan officials were warned more than four decades ago that one of its doctors was fondling patients during medical exams, but he continued working there despite a demotion and went on to allegedly abuse again as a physician with the school’s athletic department, records obtained Friday by The Associated Press show.

In 1980, the late Dr. Robert E. Anderson was pressed to step down as head of the University Health Service amid such concerns, according to a statement that his former supervisor gave to a campus detective who had started investigating the physician more than a year ago following a complaint from a former university wrestler.

When the detective told Tom Easthope, a former university administrator who oversaw Anderson’s department, that he was investigating “inappropriate behavior” by Anderson, Easthope replied, “I bet there are over 100 people that could be on that list,” according to the records.

Easthope told the detective that he had confronted Anderson about “fooling around in the exam rooms with the boy patients” and told the doctor, “You gotta go.” He said the doctor didn’t deny the allegations against him. By 1980, at least two students had made complaints to Michigan officials about Anderson inappropriately touching them, according to interviews and records.
