A person of interest was reportedly being questioned by New York City police on Saurday night in connection with a series of slashing attacks on the city's subway system.
No charges were yet filed, reporter Yan Kaner wrote on Twitter.
Earlier Saturday, the New York Police Department announced that 500 more police officers will be patrolling subway stations after the fatal stabbings of two homeless people plus two other victims in the previous 24 hours.
"We will immediately commence a surge of officers to patrol both above and below grounds to ensure that everyone that rides on our transit system on a daily basis not only is safe, but just as importantly, feels safe," NYPD Commissioner Dermot Shea said in a news conference Saturday afternoon.
"This surge will result in an additional 500 officers, which is a significant increase in the staffing of our transit bureau, and they will be deployed immediately throughout New York City."
TERRIFYING WEEK INCLUDES 5 NYC SUBWAY SLASHINGS AND BUS DRIVER ASSAULT
Shortly before midnight on Friday, an adult male was pronounced deceased after being stabbed in the neck and torso on the A train. About two hours later in the early hours of Saturday, an unconscious 45-year-old female with multiple stab wounds was transported to a local hospital where she was pronounced deceased.
Both victims were found on opposite ends of the A train line, slumped in pools of blood under the subway seat.
A 67-year-old man and a 43-year-old individual were also stabbed on the A train in the last 24 hours, though their injuries do not appear to be life-threatening.
NYPD Chief of Transit Kathleen O'Reilly said Saturday that at least three of the incidents appear to be connected and the department is looking into whether all four stabbings were committed by the same individual.
The surviving victims are helping police identify the attacker. Preliminary reports indicate he is a "lighter skinned male stranding five-feet tall and wearing a face mask."
The stabbing spree prompted commuters at the A train's Far Rockaway Mott Avenue station to call for law enforcement to increase patrols.
"It's scary. It's really scary. I've never felt safe on the subway, but I've always known I had to take them," 17-year-old Marissa Augustus said.
33-year-old Maurice Moore said police officers are nowhere to be found in the subways after 5 p.m.
"When I go home late, there's no cops here," Moore said. "between the hours of 8 in the morning to 5 in the afternoon you see them, but you don't seem them after that."
NEW YORK CITY SHOOTINGS, HOMICIDES SOARED IN 2020, CRIME DATA SHOWS
The slashings that occurred Friday and Saturday morning come after a spate of seemingly random attacks in NYC's subway stations.
Despite a precipitous drop in ridership due to the coronavirus pandemic, violent crimes such as assault, rape, and homicide increased through mid-November last year compared to 2019, according to the New York Times.
Despite the increase in crime, Mayor Bill de Blasio insisted this week that the subways "have gotten safer and safer" compared to even more recent years.
"We had an incredible and total disruption in 2020, our entire lives are turned upside down, a global pandemic, a perfect storm," de Blasio said at a news conference Tuesday.
"I am convinced that we can make sure the subways are safe and that more and more people are going to come back to the subways, and if we need to shift NYPD personnel more to the subways, we absolutely will."
