The puppeteer behind the popular "Sesame Street" character Elmo has resigned after a second allegation that he sexually abused underage boys.

Twenty-four-year-old Cecil Singleton claimed he met Kevin Clash, 52, on a gay chat line. He said the actor engaged in sexual behavior with him when he was 15.

The allegations are the second such to surface in the past few weeks against the famed puppeteer. Earlier this month another man said he was involved in a sexual relationship with clash at 16.

That man later recanted his story but not before reiterating that the relationship was sexual in nature and took place when he was underage.

Singleton said he had no idea what Clash did for a living until he Googled his name. He is suing him for $5 million.

"I remember confessing to him while we were eating that I wasn't 18, but that I would be turning 16 in the near future," he said. "If I had known that this was a recurring thing or that I wasn't special and this wasn't a unique circumstance, I would have said something much sooner."

Clash had earlier taken a leave of absence from the show when the first allegations surfaced a few weeks ago. In a statement, Sesame Street producers said the circumstances surrounding Clash's personal life had become a distraction.

The growing controversy led Clash to conclude that he could no longer be effective in his job.
