Three people were killed and another 10 were injured in an overnight shooting involving multiple gunmen at a Brooklyn nightclub, police said Sunday. The dead were identified by the New York Police Department on Sunday night as Marvin St. Louis, 19, of Brooklyn; Amadou Diallo, 27, of Upper Manhattan; and Jamel Childs, 35, of Brooklyn.

A mass shooting overnight at a club in Brooklyn left three people dead and another nine wounded, police officials and the mayor said Sunday morning.

Two of the three people killed in a bar shooting in the New York City borough of Brooklyn were among the four shooters who opened fire inside the building, the city's police commissioner said Monday.

What began as a dispute inside the packed nightclub escalated when multiple gunmen opened fire, unleashing chaos before fleeing into the streets.
