The girl told staff members that classmate Steven Moore, 16, raped her inside a bathroom at the school in November, but officials said they didn't notify police because they wanted to investigate her story themselves.

Police said the victim sat in the office of then-Principal Christopher Smith for more than two hours and was told to write a report about the incident while the suspect was allowed to leave the school.

Smith was charged Monday with failure to immediately report child abuse or neglect, a Class B misdemeanor.

"Any person who has reason to know that a child may be the victim of child abuse or neglect is required to immediately make a report to either the Department of Child Services or a local law enforcement agency," read a release from the Delaware County Prosecutor's Office. "As principal, Mr. Smith was in charge of the building and the duty to comply with the law… was ultimately his, and only his, responsibility."

If convicted, Smith could face a maximum of 180 days in jail.

Smith was reassigned within the district after a two-day quality review of Muncie Central High School conducted by the Indiana Department of Education in December deemed its overall performance judged unacceptable.
