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

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

Acting Superintendent Frank Prazenica told a Pittsburgh newspaper police are investigating. The substitute isn’t currently working in the district.

Police said 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.

Another Pittsburgh paper reported Chief Mike Diebold described the behavior as physical, but not sexual.

Police haven’t publicly identified the teacher.

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