Man killed in NYC subway station shooting, officials say

A man was killed in a shooting at a Midtown Manhattan subway station Saturday, officials say.

It happened on the northbound E train platform at the Seventh Avenue station near West 53rd Street just before 12:30 p.m.

According to authorities, the victim was shot in the chest and taken to a local hospital in critical condition, where he was pronounced dead. The victim has not yet been identified.

No arrests have been made. The investigation is ongoing.

One witness said she and her daughter had just boarded the train and sat down when they heard multiple shots being fired on the platform.

"All of a sudden I heard a shot, and then there was like a mass exodus. Everyone started running out, and then there was at least probably three more [shots]," the daughter said.

The MTA says due to an NYPD investigation, C and D trains are bypassing Seventh Avenue station, and E trains are running on the F line from West Fourth Street-Washington Square to Jackson Heights-Roosevelt Avenue.
