Elgut picked up the girl and “inappropriately touched her” behind a column where he had placed her, police said.

The girl screamed and Elgut ran away, police said. Police said officers found Elgut nearby 20 minutes later after broadcasting a description of him to the public.

Elgut was charged with first-degree sex abuse, endangering the welfare of a child, and criminal possession of marijuana. He is to be held overnight at the Fifth Precinct and will be arraigned Monday at First District Court in Central Islip.
