NEW YORK, Nov. 17 (UPI) -- Police in New York City have released footage of the man suspected of killing 61-year-old Wai Kuen Kwok by pushing him in front of the D train at a Bronx subway station.
"This will be a 24/7 operation until we identify who did this and bring them to custody," promised Chief Joseph Fox at a Metropolitan Transportation Authority meeting on Monday.
Kwok was pushed in front the train just prior to 9 a.m Sunday morning at the East 167th Street station. His apparent assailant immediately fled, escaping onto an MTA bus.
Security footage shows the man exit the bus and calmly smoke a cigarette just minutes after Kwok's death.
Police have no leads or indication of a motive at this time. Police do not believe Kwok knew the man who pushed him.
