An active shooter situation unfolded late Monday afternoon at 345 Park Avenue, triggering a massive emergency response and leaving at least three people injured, including a police officer and two civilians.
Authorities confirmed the shooting around 6:41 p.m. EDT, prompting a Level 3 Mobilization, which brings a large number of NYPD officers and specialized units to the scene. According to early reports, the shooter was inside the building and armed with a rifle.
Police established a perimeter around the area as the suspect, described as a male wearing tan clothing, was last seen near the 32nd floor elevator. Other reports earlier in the incident described a suspect in a suit and bulletproof vest, suggesting the possibility of multiple or misidentified individuals in the chaotic early moments.
As of 6:53 p.m., emergency services reported three confirmed patients:
One NYPD officer and one civilian are in critical condition
A second civilian sustained serious injuries
Authorities declared a mass casualty incident, leading to the rapid deployment of additional emergency resources, including:
K-9 units
Bomb squad
Heavily armed police teams
The building was swiftly evacuated starting around 6:49 p.m., with officers coordinating the safe exit of civilians under the protection of tactical teams.
Shortly before 7:00 p.m., police reported they had a potential suspect stopped at 51st Street and Lexington Avenue, not far from the scene. Officers are actively working to confirm the identity and connection of the individual to the shooting.
Radio communications between units, made available to the public, reflect the fast-moving and high-stakes nature of the response. It is not yet clear how the shooting began or whether there are additional suspects or threats.
Authorities continue to investigate the incident, and more updates are expected as the situation develops. Anyone with information is urged to contact the NYPD tip line.
The names of the injured have not been released pending notification of families. The NYPD and FDNY are asking the public to avoid the area around Park Avenue and 51st Street while operations continue.
