Elmo puppeteer Kevin Clash has resigned from Sesame Street in the wake of allegations that he had sex with an underage youth.

A second person has come forward accusing Clash with sexual abuse. The lawsuit alleges that Cecil Singleton, then 15 and now an adult, was persuaded by Clash to meet for sexual encounters.

The first allegation was on Nov. 12, Clash had requested a leave of absence following the charge by a man in his early 20s that he had a relationship with Clash when we was 16.

The next day Clash’s accuser recanted his charge, describing his sexual relationship with Clash as adult and consensual. Clash responded that he was relieved that this painful allegation has been put to rest.

Clash, who had been on Sesame Street for 28 years, created the high-pitched voice and child-like persona for Elmo.

He won 23 daytime Emmy awards and one prime-time Emmy.
