A man was busted with 20,000 fentanyl pills on him in Manhattan – and released back to the street, police and sources said Sunday.

Manuel Pagon, 49, was arrested at 11th Avenue and West 30th Street in Chelsea around 2 p.m. on Friday, cops said.

He was found in possession of “approximately 20,000 multi-colored M-30 fentanyl pills,” court records show.

Pagon was charged with criminal possession of a controlled substance in the first degree, records show. He was then released on his own recognizance, police sources said.
