A Morgan County teacher and coach has been placed on paid leave while investigators look into accusations that he sexually assaulted a 16-year-old female student in his home. Authorities in the Monrovia district are withholding the man’s name because no charges have been filed. School officials were notified of the alleged assault by the girl’s parents on Monday. According to the girl, the incident occurred May 29 after she was asked to babysit for the teacher. A former student said the teacher was disciplined last year for inappropriate behavior involving female students.
