EAST LANSING, Mich. (AP) - A Michigan State University official is facing four charges in an investigation into the handling of complaints against the former sports doctor Larry Nassar, who was convicted of molesting women and girls in his care.

William Strampel, who was dean of the College of Osteopathic Medicine until late last year, was charged Tuesday with a felony, a high court misdemeanor and two misdemeanors. After a judge authorized the charges, a state police detective declined to tell reporters what charges Strampel is facing, saying a news conference is scheduled for later.

Strampel is due to be arraigned in the afternoon.

The 70-year-old Strampel told police last year he never followed up after ordering Nassar in 2014 to have a third person present when providing treatment to "anything close to a sensitive area." Nassar will spend his life in prison for molesting patients under the guise of treatment.
