An internal investigation was launched Thursday into allegations that a DeKalb County assistant principal showed a lewd cellphone picture to a student, a district spokesman told the AJC.

The assistant principal at DeKalb Elementary School of the Arts allegedly showed the fifth-grader the photo while trying to determine who sent obscene photos to another student's phone. But the girl's family says the assistant principal should not have shown her the picture, and the family alerted the school system Thursday, according to Walter Woods, district spokesman.

"This is obviously a very serious issue," Woods said by phone Thursday afternoon. “What we’re trying to determine is if our policies and procedures were followed, and if not we’ll take prompt and appropriate action."

The girl's family contends the school administrator tried to bully the girl into admitting she had sent the photo. Family members held a news conference Thursday at the office of their attorney, Mawuli Davis.

"It's so inappropriate that [the assistant principal] needs to either resign or she needs to be removed from her position at this time," Davis told Channel 2 Action News.
