A repeat slasher — who has been freed without bail in two other stabbings — struck again Wednesday morning, knifing a man repeatedly in the Times Square subway station and shoving him onto the tracks, police sources said.

The 27-year-old maniac got into a fight with a 52-year-old man around 11:40 a.m. on the N subway platform, the sources said.

During the struggle, he stabbed the older man twice in the back and once in the neck and then pushed him onto the tracks, police said.

The victim didn’t make contact with a train, but he was taken to Bellevue Hospital in stable condition for treatment of the knife wounds, cops said.

Police recovered a knife at the scene.

Quick-thinking cops had used a tourniquet on the victim’s arm to stem the bleeding.

“They saved his life,” a transit cop told The Post.

The stabber, who wasn’t immediately identified, is expected to be charged with attempted murder, the sources said. 

It was his third arrest for a stabbing, police sources said.

He was busted on July 31 for allegedly stabbing a man in Brooklyn, cops said.

Then, he was nabbed on Nov. 10 for slashing a kitchen worker in the head at BoCaphe at 222 Lafayette Street, the sources said.

In both cases, he was released without bail.

Manhattan prosecutors asked for $50,000 bail or $150,000 bond but Judge Lumarie Maldonado-Cruz sprung him on supervised release, according to the DA’s Office. He was charged with first-degree assault.

“How does someone get released after two stabbings?” said a Manhattan cop. “This is the third time he stabbed someone in less than six months. Innocent people are not safe in New York.”
