Five people—including the suspected perpetrator Devon Tamura and NYPD officer Didarul Islam—were left dead at an office building in Midtow.

FBI Deputy Director Dan Bongino said agents from the bureau’s New York field office were responding to the area to provide support.

Officials said the gunman fatally shot himself after his attack, which set off a chaotic scene that rippled out into the heart of Manhattan during rush hour.

At a Wednesday press conference, New York City Democratic mayoral nominee Zohran Mamdani defended his previous calls to disband the NYPD's Strategic Response Group—an elite unit that recently responded to a mass shooting that left four dead in a Manhattan skyscraper.
