CHARLOTTE, N.C. -- A former Charlotte-Mecklenburg Schools substitute teacher accused of having inappropriate contact with a student will face his charges in Superior Court.

Lamont Deshon Barrett, 31, is facing 15 charges of indecent liberties with a student, as well as two charges of distributing obscene material to students. Mint Hill Police said Barrett, who was a substitute teacher at Rocky River High School, showed a 16-year-old male student pornographic videos while at school.

Additionally, officers continued to identify more victims after the initial charges. Three more victims added eight additional counts of indecent liberties with a student and one count of disseminating obscene material.

Authorities said the additional victims are between 16 and 18 years of age.

CMS requires background checks for substitute teachers, although North Carolina state law doesn't require them.

"Our students in North Carolina deserve to have a teacher that's been vetted," said a state school board attorney.

Barrett is scheduled to go before a judge December 7.
