Harrowing video captured a shoeless madman viciously stabbing another straphanger to death aboard a Queens train, sending terrified riders scrambling off the subway car – as the maniac was slapped with murder charges Thursday for the unprovoked spurt of violence. 

Jyrell Thomas, 25, allegedly whipped out a knife and plunged it into Mesias Lojano, 59, without warning – stabbing him three times in the torso and once in the neck – on board the packed southbound J train approaching Woodhaven Boulevard around 5:20 p.m. Wednesday, police and sources said.

The gravely wounded Lojano, of Ozone Park, was rushed to Jamaica Hospital Medical Center, where he later died, police said.

“My father was always a man of faith and he was taken away from us,” the victim’s heartbroken 29-year-old son, William, told The Post in Spanish Wednesday. 

“He was a good friend to everyone. He helped everyone.”

Lojano was on his way home from his construction job when he was brutally assaulted, according to William, who had been living the last few months with his dad.

“I shared so many good times with him. I have a hole in my heart now,” he said. “I saw the video. I want justice.”

Disturbing video posted by a straphanger to Facebook shows panicked commuters frantically fleeing the rush-hour train – where a shoeless and hooded Thomas is seen knifing Lojano repeatedly while he’s on the ground of the subway car, near its doors.

The victim tried to shield himself from the blade – with his hand covered in blood as the callous stabber pulled him by his hoodie out of the car, left him on the platform and then ran off.

The knife-wielding attacker then rushed down the stairs of the elevated station – behind other commuters including a mother and child – as the witness filming the incident yelled in English and Spanish for someone to grab the weapon.

A group of men, including the person filming, then ran after the suspect – who sprinted out into the street and finally perched himself on a garage roof, before police cuffed him.

Thomas – a Bronx resident who did not know Lojano – was also charged with criminal possession of a weapon and hospitalized, according to police, though it was not clear why.

The deadly violence initially appeared to have stemmed from a dispute, but police confirmed Thursday the attack was unprovoked.

The beloved Lojano — a native of Ecuador — was a loving father of six children, who neighbors believe was attacked at random.

“I was shocked,”neighbor Francesca Martinez said. “For me, it’s sad so you can imagine how hard it is on his family.  It’s a tough situation for them to go through. It’s a big loss.”

“I know [he] would [not] do anything to provoke somebody so I believe that,” she added.

Another neighbor, Robert Camara, called Lojano’s killing a “shame.”

“If you die of natural causes, that’s one thing but when you die when you are not supposed to, that’s horrible,” he said. “I do not trust the subway at all. … It’s unsafe, plain and simple.”

Thomas has one previous arrest from early September – for allegedly stealing $23 worth of merchandise from a Bronx Target store and then attempting to flee from cops, according to cops and sources.

He was charged with petit larceny, obstruction of governmental administration and criminal possession of stolen property, the sources said.
