Three people shot outside NYC subway station

Three people were shot just outside a Bronx subway station Monday afternoon, police said.

The gunshots rang out around 3:25 p.m. on street level at the B and D subway station at East 170th Street and Grand Concourse, officials said.

A 16-year-old was shot in the left leg, a 22-year-old was shot in the left shoulder and a 23-year-old was shot in the right leg.

All three are expected to survive.

Police found shell casings inside the station, police sources said. The men were arguing with two other guys when one of the duo pulled out a gun and started shooting.

The shooter remains on the loose.

An investigation is ongoing.
