SPRINGFIELD, Mass. (AP) — A former junior varsity volleyball coach at a Massachusetts high school has pleaded not guilty to having a sexual relationship with a 15-year-old girl.

Michael Rash was arraigned Wednesday in Hampden Superior Court on four counts of rape and abuse of a child aggravated by age.

The 24-year-old Rash was a volleyball coach at Agawam High School but was not on the faculty at the school.

He was allowed to remain free on $1,000 bail with electronic monitoring.

Rash was arrested in June after the girl's mother suspected her daughter was engaged in a sexual relationship based on phone and computer records.

The Republican (http://bit.ly/1qAcxKv ) reports that Rash's attorney refused comment after the arraignment.
