Shocking moment subway slashing victim drips blood and screams for help as passengers do NOTHING

A New York City subway passenger screamed for help after being violently slashed by a man on the train as her fellow passengers did nothing, footage shows.  

The attack, which left the woman with blood dripping down her leg and needing an emergency tourniquet to stem the bleeding, took place on the Lexington Avenue line on Sunday around 4:15pm.  

The woman, 28, tried to film her attacker as he nonchalantly walked through the carriage following Wednesday's attack on three women. 

The alleged attacker, 28-year-old Kemal Rideout, was arrested on Tuesday and arraigned on Wednesday for violently attacking three women just minutes apart at the Brooklyn Bridge-City Hall and 86th Street stations on Father's Day. 

The victim in the video can be heard screaming 'call 911! Somebody call 911' and 'pull the emergency brake! Pull the emergency brake!' but seated passengers just looked in her direction dumbfounded.

One victim who recorded the suspect calmly walking through the train required multiple stitches to her leg 

The video pans down to show the gaping wounds on her leg and the blood dripping to the subway floor.  

The victim seen in the footage, who has remained anonymous, told ABC News: 'I was on the train, texting my boyfriend,' when 'Some random guy walked past me and sliced me — I don’t know what he used — and nonchalantly walked away. My body was in shock. I didn’t feel the pain right away.'

'My first instinct was to get a video of him and then looked down and saw the blood coming down' she added.

The woman, who was the most seriously injured of the victims, required a tourniquet to close the deep wound before she was rushed to Bellevue Hospital.

'He was walking away slowly. He was walking nonchalantly. He didn't run. He brought no attention to himself at all. You could see him going through the door. He was at the tip of the door. He looked back. He saw my daughter filming. He went through and shut the door,' the woman's mother told the New York Post.

'Her mental state will never be the same.'

The first victim, Bianchelly Diplan, 19, was walking out of the 86th Street station on her way to Paris Baguette to pick up a cake when she felt the back of her leg get cut so deeply she required 19 stitches, as she became one of the many New Yorkers to experience random slashings.

'I noticed him staring at me,' she told the New York Post. 'He was staring at me [from 125th Street] until 86th Street, so a good four or five minutes.

Rideout has been accused of slashing three women at the Brooklyn Bridge-City Hall and 86th Street stations on Father's Day. He has been charged with three counts of felony assault and is being held without bail at Rikers

'I just felt a little weird, a little tense. He seemed a little off. Just the way he walked, his body language was off. You know when you have that gut feeling? He seemed off.'

The teen said she came face-to-face with her attacker after he cut her and 'he just stared at me then walked away.'

'I just started crying. I was in shock. He didn't say anything. He went back down the stairs and I could see he was walking on the platform,' she told the outlet.

Another woman, 48, was slashed in the right leg in the same station on the platform before Rideout dashed back into the downtown 4-train around 4.15pm. 

Fifteen minutes later, Rideout allegedly attacked a 28-year-old victim in the Brooklyn Bridge-City Hall station, police said.

The woman who shot the footage was the third victim. 

Rideout was eventually apprehended near a bus stop in Harlem on Tuesday. Cops spotted him after recognizing his shoes and he was carrying a bag with the outfit he was wearing on the train on Sunday. 

Chief of Transit Michael Kemper said at a press conference that he was 'proud' of his officers and 'depressed' by the incident.

MTA CEO Janno Lieber praised the police for catching Rideout, saying: 'It is a great comfort to our riders and everyone in our region to know that the NYPD has subway riders' backs.'

The career criminal had four priors outside of the city before Sunday's trio of attacks.

'For forcible touching in Norwich 2016, for assault again in Norwich in 2012, for attempted rape in Varick, New York, and 2011 for criminal mischief in Riverhead,' Chief of Detectives James Essig said at a press conference.

Rideout is being held on Riker' Island without bail.
