In a statement, attorney Adam Frank said that the student, DeShawn Rasheed Jones, 17, of the 6000 block of Laurel Wreath Way, denies the allegations against him.
"The public must remember that there are two sides to every story and there will be evidence that will shed light on Mr. Jones’ innocence," the Towson-based attorney said. "He and his family would ask that you please refrain from any judgment until all of the facts are brought out during trial."
Jones was arrested on Feb. 5 after police were notified by the mother alleging her daughter had been sexually assaulted in the building's first-floor choir room while cutting class.
After being detained by police, Jones confirmed there was sexual contact between himself and the girl, according to court documents.
Jones is being charged as an adult, and faces second-degree rape, assault and false imprisonment charges in connection with the incident.
Jones, who is being held on $500,000 bond, is scheduled for a preliminary hearing in Howard County District Court on March 8, according to online court documents.
Correction: An earlier version of this story said the incident occurred in the third-floor choir room. The incident occurred on the first-floor, according to Howard County Public Schools spokesperson Rebecca Amani-Dove.
