ANN ARBOR, Mich. (AP) — The University of Michigan says it has received more than 100 “unique complaints” about a late physician accused of sexual abuse by former patients, including athletes who encountered him as a team doctor.

In a statement Friday, a university spokesman urged others to contact the university. The university announced last week that it was investigating abuse allegations against Dr. Robert E. Anderson by five former patients.

In a report published earlier Friday, The Detroit Free Press reported that a former patient said Anderson wrote letters certifying students were gay so they could avoid military service during the Vietnam War in exchange for sexual contact.
