The Department of Child and Family Services is investigating after a gym teacher at a south suburban high school was accused of inappropriately touching a student and was charged with a misdemeanor. School officials at Thornton High School in Harvey confirmed the male teacher in question has been on administrative leave since the incident was reported in May. The student and her mother, whose identity WGN News is concealing because of the nature of the charges, said the teacher has a reputation for flirting with young girls and in some cases, inappropriately touching them. He was also the student's softball coach.
