Commuters and officials are calling for action in the wake of the latest subway attack, saying it has become a persistent problem. 

Authorities say a 60-year-old woman was stabbed in the back Wednesday morning at the Pennsylvania and Livonia Avenue subway stop.

Investigators say she got into an argument with a man who then pulled out a knife and attacked her before taking off. 

The woman is expected to be OK. Police say they are still looking for the suspect. 

However, that wasn’t the only attack that was reported on Wednesday. 

Multiple incidents were reported within a few hours of each other, including two at the busiest station-- Times Square on 42nd Street. 

NYC Transit interim President Sarah Feinberg released a statement, saying in part, "The mayor must act. The transit system needs an injection of additional mental health resources and a visible police presence on platforms and trains to deter crime and better support our customers returning to the system. New York’s economic recovery depends on it.”
