Kevin Clash, Elmo voice accused by third man of underage sexual contact: More accusations

One accusation after another... for former Elmo puppeteer Kevin Clash. A third man has come now forward, with disturbing allegations. 

Tuesday's lawsuit alleges clash had sex with a teenage boy he met on a gay chat line, in 2000. This is the third alleged victim to come forward and is identified only as "John Doe." He says the two had a sexual relationship until he was 18. 

And "John Doe" says he has suffered emotional and psychological problems from the abuse. Kevin clash has denied any wrong doing. He resigned as the voice of Elmo on "Sesame Street" earlier this month. 

A rep for Clash released a statement Tuesday saying "The federal cases filed against Kevin Clash are without merit. The cases and Mr. Clash's reputation will be defended vigorously."
