NEW YORK (AP) — The puppeteer who performs as Elmo on “Sesame Street” is taking a leave of absence from the iconic kids’ show in the wake of allegations that he had a relationship with a 16-year-old boy.

Puppeteer Kevin Clash has denied the charges, which, according to Sesame Workshop, were first made in June by the accuser, who by then was 23.

“We took the allegation very seriously and took immediate action,” Sesame Workshop said in a statement issued Monday. “We met with the accuser twice and had repeated communications with him. We met with Kevin, who denied the accusation.”
