A suburban Philadelphia math teacher has been charged with having a sexual relationship with a 14-year-old student.

Thirty-three-year-old Jessica Streeper of Doylestown is charged in Montgomery County with institutional sexual assault, involuntary deviate sexual intercourse, corruption of minors and related offenses.

Police in Norristown said an anonymous caller alerted them to the alleged relation between the student and Streeper, a teacher at Eisenhower Science and Technology Leadership Academy. Authorities allege in a criminal complaint that the eighth-grader told them that he had sex with Streeper in her car and in her home.

Streeper remained in custody in lieu of $100,000 bail. A number listed for her had been disconnected and the county public defender's office, listed in court documents as representing her, said Friday that no attorney had been assigned.
