New York prosecutors say a woman charged with murdering a man who was pushed in front of a subway train told them she did so in revenge for the 9/11 attacks.
Erika Menendez, who is 31, is accused of second-degree murder as a hate crime.
Security film shows someone running from the scene shortly after the attack in Queens.
The victim, 46-year-old Sunando Sen originally came from India. The woman reportedly said she hated Hindus and Muslims.
It is the second such fatal attack in the city this month. A 30-year-old man was charged with murder after a man was pushed in front of a train in early December.
Police say there is no evidence the two attacks were related.
The authorities argue little can be done safety-wise beyond warning people to stay away from the tracks on platforms.
Murders in New York overall have dropped dramatically this year.
