Fencing perv foils justice

A two-time Israeli national fencing champion sexually assaulted a 13-year-old Brooklyn prodigy he was coaching, authorities said.

Nitai Kfir, 32, was arrested in the fall of 2011 for twice having sex with the girl inside his Queens apartment — once just hours before she competed in a match, according to court documents.

Kfir, a former St. John’s University fencing standout, got off with a five-month jail stint and probation but fled the country a day after his release Aug. 17. Authorities believe he is now in Israel.

The coach-student relationship turned sexual in October 2011 when Kfir told the girl, whose name is being withheld by The Post, to meet him at a Starbucks. He then took her back to his place, where they had sex and she spent the night, according to court documents.

The second tryst occurred when Kfir picked the girl up and told her parents he would take her to a fencing competition.

Kfir coached for at least five years at the Fencers Club, a Manhattan institution that bills itself as the oldest fencing club in the country.

The victim, herself a national fencing champion, trained at the club since she was a child.

Kfir was charged with rape and endangering the welfare of a child after the victim’s mother discovered the illicit relationship in November 2011 and called cops.

He plea-bargained in May to felony criminal sexual act and was sentenced to five months in jail and 10 years’ probation. The deal with the Queens DA called for Kfir to register as a Level 1 sex offender after his release, and he was ordered not to have any contact with the girl.

The victim and her family agreed to the plea deal because it kept her from testifying against her coach in court, prosecutors said.

But a day after Kfir got out of jail, he fled the country, sources said.

It’s unclear how the Israeli native, who came to the United States legally about a decade ago, was able to flee undetected.

Former Brooklyn prosecutor Eugene O’Donnell, a John Jay College of Criminal Justice professor, says the case sparks concern.

“The issue is how a foreign national can just flee and leave all the harm he causes behind,” O’Donnell said. “It raises a systematic question. It’s not like he was on probation for shoplifting. This is a very serious crime.”

The victim is now suing Kfir and the club in Brooklyn Supreme Court for unspecified damages. She claims the club was negligent for failing to properly supervise Kfir.

Kfir was fired after his arrest, and the 500 members of the club were notified immediately, the club’s executive director, Elizabeth Cross, told The Post.

“It came as a complete shock,” Cross said of Kfir’s arrest. “As soon as we found out, it was dealt with instantly.”
