A 14-year-old Washington state high school student accused of sexually assaulting three other students on a football team bus trip pleaded not guilty to rape Thursday.

Police say the boy penetrated three other boys with his finger Sept. 6 on the bus ride back from a Wenatchee High School freshman football game in Spokane. The boy's parents and their attorney, Brandon Redal, say the incident was horseplay and not criminal.

The Wenatchee World reports (http://bit.ly/YjzTHq ) a trial would be heard by a Chelan County Superior Court judge. If convicted of second-degree rape, the teen could face a year or more in detention.

The boy has been held in juvenile detention since his Sept. 10 arrest with bail set at $50,000.
