Jean Kleckner, of Reading, was arraigned Thursday after allegedly admitting she had inappropriate sexual contact with a teenage girl.
The 47-year-old was the head coach for the Muhlenberg Junior High Field Hockey team at the time of the alleged abuse, and also served as a substitute teacher for the Muhlenberg School District. That's the same district the victim attended, according to authorities.
Detectives say Kleckner was a family friend of the victim and the abuse began in 2008, when the girl was just 16.

In a written statement, Kleckner admitted to detectives that she did have inappropriate sexual contact with the victim.
She surrendered to authorities and was arraigned on corruption of minors and endangering the welfare of a child charges. Kleckner was being held Thursday on $50,000 unsecured bail, according to court records.
