The coach, who was identified as  Nicolas Morton, 31, has been accused of forcing players to expose themselves.

He threatened to cut them from the team if they did not comply to his demands.

Nicolas Morton, 31, who had worked at the $60,000-a-year Packer Collegiate Institute, also groped at least three of those boys’ genitals, according to details released along with a 20-count sex crime indictment against him in Brooklyn Supreme Court, reported New York Post.

Fed up with Morton’s alleged sick abuse, the kids, aged 12 to 14, rallied to expose their coach, said Gwen Barnes, who works in the Brooklyn District Attorney’s special victims bureau, told the newspaper.

“Over the summer, this was finally reported, the boys then bravely came forward and stood up for themselves and each other,” Barnes told a judge during Morton’s arraignment Thursday afternoon.

The coach was arrested on Thursday.

Before he was fired, Morton worked as a varsity baseball coach at the Packer Collegiate Institute and in its admissions office.

He is a Packer alumnus.

The next hearing in the case will take place on December 13.
