ALLENTOWN (AP) — A 15-year-old boy is being charged with sexually assaulting a girl in the basement of an eastern Pennsylvania high school.

Lehigh County District Attorney Jim Martin tells The Morning Call (http://bit.ly/1cn0mdU ) that charges are going to be filed in a juvenile petition. He says it happened in the basement of Dieruff High School in Allentown earlier this month.

Martin says the victim is a 16-year-old girl.

Allentown schools solicitor John Freund wouldn't comment on the case. But he says the district is conducting its own investigation.
