The suspect can be seen, however, attacking one of the passengers who appeared to step in to help after a first victim was allegedly cut by Chambers' knife.
A spokeswoman for the Office of the Deputy Commissioner of Public Information (DCPI), Detective Sophia Mason, said the attack took place on July 5 at 52nd street in Queens and was unprovoked.
The suspect produced a knife and stabbed a 71-year-old male and a 73-year-old male. Both victims were taken to Elmhurst Hospital and were in stable condition at the time.
The suspect was arrested at the 52 Street station stop and a knife was reportedly recovered from his person, police said.
No official court date was provided.
