Two people died after a Manhattan knifeman went on a horror stabbing spree Monday morning. 

A total of three people were stabbed, in what is said to have been an unprovoked attack, according to the NYPD.

One victim, an unidentified 36-year-old construction worker, was stabbed around 8.20am on W. 19th St. near Tenth Ave. in Chelsea, according to police. 

He was stabbed in the abdomen 'without warning' and rushed to Bellevue Hospital, where he was later pronounced dead. 

An unnamed Asian 68-year-old man, who was fishing in the East River, was then stabbed 'multiple times in the body' around 10.27am.  He died at the hospital. 

A third victim, a 36-year-old black woman, was stabbed around 10.55am at E. 42nd St. and First Ave. in Murray Hill.

The unidentified woman was also taken to Weill Cornell Medical Center where she remains in critical condition. 

The suspect, a 51-year-old Hispanic man, was arrested soon after on East 46th Street and First Avenue after a cab driver called the police. Charges against him are pending.

In addition to the cab driver, several good Samaritans and NYPD Officer Robert Garvey helped tracked down the knifeman. 

'If Officer Garvey was not there, these random acts of violence, this person conceivably would have continued those random acts of violence,' Mayor Eric Adams said. 'So, he saved the lives of fellow New Yorkers.' 

Two knives were recovered at the scene, the New York Daily News reports.

The suspect is said to have a string of previous arrests, including four burglaries between December and January, followed by a grand larceny arrest in October.

According to the report, the disturbed individual also has arrests in other states, including Florida, Ohio and New Jersey.

Witnesses alerted cops that he was in the area, as officers later found him with blood on his clothing, according to police.

The suspect is reportedly a resident of the Bellevue Men's Shelter, according to the New York Post

A witness, Baha Biten, who was at the consulate building at the time, said he 'saw this homeless guy walking with a purse.' 

'And then I saw this guy in the car telling him "Stop, drop the bag! Stop!".

'Of course he didn't listen and then all of a sudden I saw the guys in suit and earphones rushing and trying to look for a suspect,' he added. 

The witness said the male suspect 'didn't resist' during his arrest, but added that he 'was not mentally ok.' 

'As of right now, these attacks seem to be unprovoked, that he just walked up to them and began to attack them with the knives,' NYPD Chief of Detectives Joseph Kenny said.

'No words exchanged. No property taken. Just attacked, viciously,' Kenny added. 

Following the horrid attacks, Adams said: 'Our hearts go out to the families, goes out to other New Yorkers who observed such a terrible action. 

'We will keep them in our prayers.' 

'Three New Yorkers. Unprovoked attacks that left us searching for answers on how something like this could happen. 

'We are still looking over his record, but there's a real question on why he was out on the street,' Adams said of the suspect.
