A little girl fell onto the tracks of a Manhattan subway station before being rescued by a cop.

The 3-year-old was attempting to board an uptown train at the Bowling Green station at around 6 p.m. Tuesday when she slipped between the platform and the subway car.

Officer Michael Konatsotis, 46, heard the horrified mom’s screams, ran over, stuck his arm into the gap and pulled the child to safety.
