GLEN BURNIE, Md. (WJZ)--A former gym teacher has been arrested on child pornography charges.

Back in April, Gregory Alan Christy, 39, was accused of having child pornography on his computer.

Since then, a forensic investigation uncovered the photos and Christy was arrested Wednesday at his Anne Arundel County home.

Christy's roommate found a video on his computer showing what appeared to be a 10-year-old girl, according to court documents.

He is charged with both distribution and possession of child pornography.

Christy was a physical education instructor at Rippling Woods Elementary in Glen Burnie from 2008 until last spring.
