Elmo a Pedo?

The puppeteer who provides the voice of Elmo is on a leave of absence from Sesame Street after denying he had an inappropriate relationship with a teenage boy.

Sesame Street Workshop says it found the allegation against Kevin Clash "unsubstantiated," and granted him leave as he takes "actions to protect his reputation."

In June, the workshop heard from a 23-year-old man who claimed that he had "a relationship" with Clash beginning when he was 16 years old, the workshop said in a written statement.

The statement did not use the word "sexual."

"We took the allegation very seriously and took immediate action. We met with the accuser twice and had repeated communications with him. We met with Kevin, who denied the accusation. We also conducted a thorough investigation and found the allegation of underage conduct to be unsubstantiated. Although this was a personal relationship unrelated to the workplace, our investigation did reveal that Kevin exercised poor judgment and violated company policy regarding internet usage and he was disciplined," the Sesame Street Workshop statement said.

"Kevin insists that the allegation of underage conduct is false and defamatory and he is taking actions to protect his reputation. We have granted him a leave of absence to do so.

"Elmo is bigger than any one person and will continue to be an integral part of Sesame Street to engage, educate and inspire children around the world, as it has for 40 years."

CNN could not reach Clash immediately for a response.  TMZ reported that Clash said his relationship with the accuser "was between two consenting adults and I am deeply saddened that he is trying to make it into something it was not."

Last year, Clash spoke to CNN about the magic of Elmo, a "mirror image" for kids.
