Several men alleging sexual abuse by a deceased University of Michigan doctor have retained law firms that are representing accusers who sued Michigan State University and Ohio State University in similar cases, attorneys said Monday.

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.
