A man carrying a rifle killed four people at a New York City office tower on Monday, July 28, including an off-duty NYC police officer, and wounded a fifth before taking his own life, officials said. The incident began at the end of the workday when reports of gunfire prompted hundreds of police to a busy office district on the storied Park Avenue, an area popular with tourists and visiting business people.

Police said the scene, an office tower block at 345 Park Avenue home to hedge fund giant Blackstone, auditor KPMG and the NFL, had been "contained and the lone shooter is dead," without providing details about the identity of the suspect. A worker from a nearby office building wept as she left the area after a local lockdown was lifted, while another described a gunman going floor to floor as staff prepared to leave for the day.

"Four people, including a New York Police Department officer, were killed in today's shooting in Midtown Manhattan," a law enforcement source told broadcaster CNN, adding that the suspected gunman died from what is believed to be a "self-inflicted injury."

Mayor Eric Adams said on X that an officer had been "struck down" and expressed his "deepest sympathies" to the family of the officer. "At this time, the scene has been contained and the lone shooter has been neutralized," police commissioner Jessica Tisch wrote on X. Another man was seriously injured and remains in critical condition, said Adams.
