A Brooklyn perv was busted for allegedly abusing a 5-year-old girl in a stairwell at her home — and cops say he may have more victims who have yet to come forward.

Abraham Samotin, 26, of Crown Heights, allegedly lured the child out of her home in the neighborhood and sexually abused her in an outside stairwell on May 16, cops said.

Samotin was arrested for the crime and charged with several sex crimes and acting in a manner injurious to a child, police said. His victim was taken to an area hospital, treated and released.

Cops released a photo of Samotin on Wednesday, urging more of his victims to come forward to police.

He is a well-known menace in his Crown Heights neighborhood, police said, with 21 previous arrests on charges ranging from burglary to theft.
