One person is dead and five others were injured in a shooting at a subway station in the Bronx borough of New York after a fight broke out late Monday afternoon, a law enforcement source told CNN.

The shooter, described as wearing a red jacket and ski mask, opened fire on passengers at a platform at Mt. Eden station after a fight, the source stated.

One person died at a hospital and the other five are hospitalized. One victim walked to the hospital, the law enforcement source said.
