Off-duty NYPD officer Tremel Davis was taken into custody Wednesday morning after allegedly pushing a female subway conductor to the ground.


The J train was stopped at Essex and Delancey Streets, where the conductor was to leave her shift. As she attempted to exit the train cabin she accidentally bumped Davis, 33, with the cabin door around 9 a.m., police said.


“A dispute ensued” between the off-duty officer and the conductor, and the cop allegedly pushed the conductor to the floor, police said.


She suffered an injury to her arm and was taken to a local hospital for assessment.


The cop was arrested charged with assault, police said.


A video captured some of the chaos on the J train Wednesday morning when bewildered straphangers wondered why they were stopped. Someone on the outside of the train alerted riders to the police activity on another car.
