Kevin Kiadii, now 25, of New York, alleges that he was 16 when he and Clash engaged in sexual contact after meeting on a gay phone chat line. According to the lawsuit, Clash initiated contact with Kiadii on the chat line in 2004, invited him to his New York apartment and sent a luxury car service to pick Kiadii up in Brooklyn.
"Upon his arrival, Kevin Clash gave Kiadii alcohol and groomed him with attention and affection," the lawsuit says.
The sex was consensual, the lawsuit says, but "as a 16-year-old child, Kiadii was not emotionally or psychologically prepared for a sexual relationship with a grown man in his forties."
Kiadii's lawsuit was filed in New York and seeks undisclosed damages. The age of consent in New York is 17.
Kiadii is represented by Miami attorney Jeff Herman, who also represents the four others who have filed lawsuits against Clash since November. Last month, Sheldon Stephens, the first man to allege that Clash had a relationship with him when he was underage, filed a lawsuit in Pennsylvania.
