ELIZABETH, Pa. -- A high school chemistry teacher in the Elizabeth Forward School District was arrested on Sunday on sexual assault charges among others.

Parents of the school district received a letter in the mail on Wednesday informing them that Brian Brosh, 40, was arrested and taken into custody by the Allegheny County Police.

Other charges against Brosh include endangering the welfare of children, involuntary deviate sexual intercourse and corruption of minors.

The charges stem from allegations that Brosh engaged in sexual relations with a 16-year-old female junior five years ago.

Jane Milner, of the Elizabeth Forward School District, said that Brosh was suspended as soon as they became aware of the allegations against him.

Police are continuing their investigation.
