LEECHBURG, Pa. — Police say nine children told investigators a substitute teacher in Pennsylvania had inappropriate physical contact with them.

Police say the incidents involving a Leechburg Area School District substitute happened from late February until last week.

Acting Superintendent Frank Prazenica tells The Tribune-Review police are investigating. The substitute isn’t currently working in the district.

Police say the children told teachers and a principal about the incidents. Police were made aware of the allegations last week when a teacher called a child-abuse hotline.

The Pittsburgh Post-Gazette reports Chief Mike Diebold described the behavior as physical, but not sexual.

Police haven’t publicly identified the teacher.

Police are asking parents to talk with their children, specifically in fourth through ninth grades.
