A woman between 50 and 60 years old and believed to be homeless was discovered dead on a subway train in New York City on Saturday, police say.

A conductor did a routine check on Saturday afternoon on the F train at Hillside Ave and 179th Street in Jamaica and saw a woman not moving in the car.

The New York Police Department says officers responded to a 911 call at a subway station where they found a woman on a train who was pronounced dead at the scene. Her cause of death is under investigation.

The NYPD is set to deploy dozens of additional officers throughout the MTA overnight starting Monday night as part of the governor’s latest plan to address safety. Gov. Kathy Hochul announced the phased approach subway safety last week during her State of the State address.
