A 30-year-old woman was taken into custody after allegedly shoving a 49-year-old woman to her death in front of a moving train at a busy New York subway station during an argument.

Witnesses said the suspect had been arguing with the victim and looked 'proud' as she was led away by officers at the Times Square-42nd St station on Monday. 

The victim had been standing on the platform when the suspect, wearing a pink shirt and scarf, lunged at her, police said.  

She was shoved onto the tracks of a southbound 1 train at about 1.20pm and was pronounced dead on the scene shortly afterward, a police spokeswoman told Daily Mail Online. 

Witnesses immediately alerted police officers, who apprehended the 30-year-old suspect in the station.

It was not immediately clear whether the suspect knew the victim, who police did not identify. 

William Aubry, the police department's chief of Manhattan detectives, said investigators were reviewing surveillance video and interviewing witnesses to determine a motive.

Many of those who saw the attack were visibly shaken. 

Some witnesses said the victim and the suspect were involved in a dispute before the fatal shove, Aubry said, but it was not immediately clear whether the women knew each other. 

'What happened here today is tragic,' Joseph Fox, chief of transit for the New York City Police Department, told reporters at the station.

Two other women may have been involved in the incident, witnesses told the New York Post.   

One witness said the suspect looked 'proud' as she was led away by officers.

'About five minutes ago, 20 police officers escorted her out,' the witness told the Post.

'Her head was up — kinda proud of what she did.' 

Another subway passenger Lindsey Ramirez wrote on Facebook that she 'saw a woman getting handcuffed, who looked like she didn't give a damn.' 

An investigation is ongoing.

Dozens of people are hit by New York City subway trains each year, although most of the incidents are accidental, according to the Metropolitan Transportation Authority, which operates the system. 

Last year, a woman was convicted and sentenced to 24 years imprisonment for fatally pushing a man into the path of an oncoming New York subway train in 2012.
