Convicted sex offender Jefferey Epstein ignored instructions to check in with the New York Police Department every 90 days and was never punished for doing so, according to the New York Post.

Epstein was labeled a Level 3 sex offender in 2011 in connection to a non-prosecution agreement he took in 2008 after a 14-year-old girl accused him of molesting her at a Palm Beach house in 2005.

A judge ruled that he would have to check in to New York police every 90 days thereafter, despite Manhattan not being his primary residence.

Based on the requirement, Epstein should have checked in to police and verified his address 34 times before he was arrested on sex-trafficking charges on Saturday, according to the New York Post.

The NYPD told The Washington Post in March that Epstein had never checked in after the judge's ruling.

Skipping checkins is in violation of the Sex Offender Registration Act, reportedly punishable by up to four to seven years in prison. Epstein was never punished.

At the time of his registration as a sex offender in 2011, the NYPD argued that Epstein shouldn't have been required to check in because New York was not his primary residence, and that Epstein claimed his primary residence was a private island in the US Virgin Islands, Little St. John, The New York Post reported.

But, a source told the Post, the location of the check ins was not determined by the NYPD. "If the judge says he has to report here, he has to report here. If he didn't, then he's in violation and they could have arrested him," the source said.

NYPD Chief of Detectives Dermot F. Shea said on Twitter on Thursday that Epstein changed his residence to the Virgin Islands before his first legally mandated check-in as a sex offender.

Epstein is now being held at the Metropolitan Correctional Center in Lower Manhattan as he awaits a July 15 bail hearing.

He was charged on Monday with sex trafficking and conspiracy. In the indictment, prosecutors alleged that Epstein molested girls as young as 14 in a sex trafficking operation that ran from at least 2002 to 2005. Epstein has pleaded not guilty.
