The sheriff's office said it issued an arrest warrant on Wednesday for Wake County resident Zachary Michael Reynolds, 23, charging him with indecent liberties with a student.
Reynolds was taken into custody the same day.
The warrant was the result of an investigation into allegations of an inappropriate relationship with a student by a teacher at Bunn High School.
Reynolds was taken to the Franklin County Detention Center and given a $15,000 secured bond.
The investigation remains active. Anyone with further information is asked to please contact Detective A. Dillon at (919) 340-4311.
