CONESTOGA HIGH SCHOOL TEACHER'S AIDE ACCUSED OF SEX WITH STUDENT BERWYN, Pa. (WPVI) -- A woman who works as a teacher's aide and coach at Conestoga High School in Berwyn, Chester County has been arrested on sex related charges. Christine Towers of Phoenixville is accused of having a sexual relationship with a 16-year-old male student. Police say at the time of the alleged abuse Towers was a teacher's aide at Conestoga High School, as well as coaching softball and other sports. When interviewed by police, the alleged victim told police he was in a sexual relationship with his teacher's aide, Towers. The victim also claims that Towers urged him not to tell police about their sexual relationship. In a letter to parents, Tredyffrin/Easttown School District Superintendent Richard Gusick writes: "When those placed in positions of supporting our children are charged with violating a fundamental trust, it is deeply disturbing to us all. The welfare of our students remains a top priority. We will continue to support all students as this case moves through the criminal justice system." Towers is charged with institutional sexual assault, endangering the welfare of children, and corruption of minors. She was arraigned Thursday morning and is now free after posting 10 percent of $50,000 bail. It was just last month that three Conestoga football players were charged with assaulting a freshman student with a broom handle. That hazing scandal ultimately led to theresignation of the school's football coach.
