News outlets report the victims of Michael Kelly filed the complaint Tuesday against him, the New Hanover County Board of Education and others.
Kelly pleaded guilty last month to child sex charges. Investigators say Kelly abused nearly 20 victims. He's worked for New Hanover Schools since 1992.
Attorney Jim Lea says they're seeking compensation for victims, better safety procedures for students and major leadership changes among administrators.
New Hanover District Attorney Ben David said Kelly told investigators the school looked into allegations of his behavior, but cleared him.
The State Bureau of Investigation is looking into claims that the administration knew about Kelly's action but failed to report them.
