Oxford police said it is not believed any of the children from the school are involved.
Allen was arrested Sept. 19 and remains housed in the Butler County Jail in lieu of a $25,000 bond.
McGuffey Montessori School released a statement regarding Allen, saying in part, “Mr. Allen was terminated in May because of his failure to perform the duties of Head of School. Other than suspecting misappropriation of funds, we were not aware of any criminal activity at the time of his termination.”
