BALTIMORE (WJZ) — A former Catonsville High teacher faces several charges for allegedly groping a 16-year-old student when he was teaching at the school more than a decade ago, authorities said.

Nathan Lee Martin, 38, of Severna Park, turned himself into police on June 22 after a warrant was issued for his arrest on charges of second-degree child abuse, fourth-degree sexual offense and sexual abuse of a minor, according to police. Last month, a Baltimore County grand jury indicted him.
