A Manhattan judge Thursday threw the book at a serial convict for a horrific attempted rape that left a woman unconscious and naked on a Harlem street — calling the attack “one of the most inhumane acts of violence” he’d seen before handing down the 50-years-to-life sentence.

Rasheen Davis, 40, was slapped with the maximum sentence on all of the crimes he was convicted of — including attempted murder, attempted rape, assault and robbery — for the sadistic March 18, 2022 assault that was caught on surveillance video.

“This is one of the most inhumane acts of violence that I’ve seen in over 30 years doing this,” Manhattan Supreme Court Justice Gregory Carro said to Davis.

“Evidenced by your history, you will remain an extreme danger to the citizens of this state.”

Carro said that the attempted murder and attempted rape sentences of 25 years to life would run back-to-back increasing the total penalty to 50 years to life in prison.

In the video, released by the NYPD, Davis could be seen putting on latex gloves and a ski mask before he attacked the 43-year-old woman from behind.

The sick fiend punched, kicked and stomped on her head, and then stripped her naked and tried to rape her limp body.

He then stole her jacket, left her by a pile of trash and fled the scene.

The victim had to be sedated in the hospital for several days after suffering a traumatic head injury and brain bleeding.

“Today, Rasheen Davis was held accountable for a horrific attack on a New Yorker,” Manhattan District Attorney Alvin Bragg said in a statement.

“I hope that this sentence delivers some measure of closure for the survivor. Nobody should have to experience this type of injury and trauma, and we will continue to prioritize uplifting survivors and ensuring they have the support and resources they need to recover.”

Davis, of The Bronx, has several prior convictions – including three on felony charges. He was on parole at the time of the attack for a 2020 robbery conviction.

And a week prior to the attempted rape case, Davis allegedly violently robbed an acquaintance, slashing him in the face with a razor blade before stealing his cash. He was charged with robbery and assault in that case.

The Legal Aid Society – which represented Davis in the case – didn’t return a request for comment Thursday.
