A former security employee for Del Laboratories Inc. has filed a lawsuit accusing the company’s ex-chairman and CEO of sexually harassing him and firing him after he complained.

Stephen Dux, 45, of Westbury, N.Y., says the harassment began when he was assigned to be then-CEO Dan K. Wassong’s driver and went to his Carlyle Hotel apartment to pick him up on April 2, 2003. The lawsuit names the company and Wassong as defendants.
