Didarul Islam, 36, was killed during a mass shooting on July 28, 2025, in the lobby of an office building at 345 Park Avenue in Midtown Manhattan. An immigrant from Bangladesh, Islam served with the NYPD’s 47th Precinct in the Bronx and was working off-duty in uniform as a security guard when he became the first person shot. He was a married father of two young sons and his wife was pregnant at the time.

Authorities say the gunman, identified as 27-year-old Shane Devon Tamura of Las Vegas, entered the lobby shortly after 6:00 PM and opened fire with an M4 rifle before going to other floors and killing three more people. A note left by the shooter referenced suspected CTE and blamed the NFL; investigators reported the attacker had driven from Las Vegas and appeared to have targeted the building. A lower receiver for the weapon was purchased by a coworker of the gunman, who is cooperating with authorities.

Islam was lauded for his actions that evening and was posthumously promoted to Detective First Grade; his funeral was held at a mosque in the Bronx and was attended by thousands. If anyone knew Officer Islam, his family, or saw activity around 345 Park Avenue that night, please share what was observed.
