A Long Island man was busted for sexually abusing a child at Boy Scouts of America events, authorities said.

Assistant scoutmaster Jonathan Spohrer was nabbed Thursday at his North Bellemore home, Nassau police said.

The 26-year-old is accused of abusing a 12-year-old boy repeatedly from January 2018 through November that year at Scout-sanctioned events and retreats, authorities said.

Spohrer was charged with course of sexual conduct against a child at his Friday arraignment at Nassau First District Court and was held on bond $13,000, cash $6,500.

His lawyer could not immediately be reached.

Boy Scouts of America rep Chris Coscia told The Post the organization is “ shocked and disgusted at this alleged behavior, which is reprehensible and runs counter to everything for which” it stands.
