A lawyer for one of Jeffrey Epstein’s accusers ripped the NYPD on Tuesday for failing to monitor the Level 3 sex offender — and said the department’s flub may have contributed to his sick porn stash.

“I’m really, really surprised that the NYPD let him get away with this, knowing he’s a level 3 sex offender,’’ said lawyer Brad Edwards — referring to the debacle exclusively reported in The Post in which the police department failed to follow up on a court order requiring Epstein to report in every 90 days.

Asked what effect the NYPD’s botched actions might have caused, the lawyer responded by noting the massive trove of porn — including some allegedly involving children — in the multimillionaire pedophile’s Upper East Side home.

“For one, I doubt that he would have been keeping these pornographic trophies, which is what it seems to be, of thousands of photos of young women in his home if somebody was checking on him and he felt there was some sort of scrutiny and accountability of being a registered sex offender,’’ Edwards said.

The lawyer added that for Epstein, “Sex was his full-time job.”

“One of the questions I’ve received many, many times is what Jeffrey Epstein actually did on a daily basis. What I’m telling you is, what he did on a daily basis is engage in these types of sex acts with young adults and children,’’ Edwards said.

“I’m also telling you that his employees’ sole responsibility was to accumulate as many of these people for those sexual perversions as they possibly could. That’s what he did.

“What he did to make his money, I don’t know. What he did legitimately outside of engaging in these sexual misdeeds, I don’t know — nor do any of the witnesses that we have ever deposed.”

The NYPD insisted to The Post in a statement, “Jeffrey Epstein was never in violation of the judge’s order as he legally changed his residency and was monitored in his new jurisdiction in compliance with” the law.

But a judge already considered the residency argument by Epstein’s lawyer in 2011 — and rejected it, ruling that the pedophile would still have to adhere to the requirements for Level 3 sex offenders, considered the worst and most at risk of repeating their crimes, while in New York state.
