A massive investigation is underway in Brooklyn after a reported subway station shooting that left four people, including at least one police officer, wounded. 

The incident happened at about 3:10 p.m. on Sept. 15 on the mezzanine of the Sutter Avenue station on the L line in Brownsville, near the corner of Sutter and Van Sinderen Avenues. The extent of the injuries are not yet known, though the New York Post reported that at least one officer was shot in the chest.

Police advise residents to avoid the crime scene while the investigation is underway. The MTA also reported that L trains are skipping the Sutter Avenue station, and that some L trains bound for Canarsie are terminating at either Bedford Avenue, Broadway Junction or Atlantic Avenue.

It’s the second shooting involving a police officer to occur in Brooklyn this weekend. On Friday, police shot a man during a standoff inside an apartment in East Flatbush.

In that incident, police said, Vilmond Jean-Baptiste, 38, who was wanted for questioning in connection with several shootings in the borough, allegedly charged at cops with a knife, leading officers to shoot him dead. No officers were injured in that incident.

Brownsville has also seen a dramatic uptick in shootings in 2024. Earlier this year, the NYPD surged additional officers into the community in an effort to quell the violence and avoid a summer shooting outbreak. 

Transit crime has also been down in recent months citywide after the NYPD surged additional officers into the subway system.
