PITTSBURGH (KDKA) – A teacher in the North Hills School District is no longer charged with sexually abusing a student.

The Allegheny County District Attorney’s office withdrew charges against Highcliff Elementary School teacher Nathan Buttenfield on Monday, according to our media partners at the Pittsburgh Post-Gazette.

Last fall, Buttenfield was charged with inappropriately touching a 7-year-old girl during gym class.

There was no explanation for why the charges were withdrawn.

The Post-Gazette reports Buttenfield’s lawyer says he hopes to return to work and have his criminal record expunged.
