Midtown Manhattan Active Shooter Report Prompts Massive Police Response in Business District
Authorities confirm that on Monday, July 28, 2025, at approximately 6:28 p.m., a gunman opened fire at 345 Park Avenue in Midtown Manhattan—home to the NFL headquarters, Blackstone, KPMG, and other major firms. The alarming active shooter report triggered an immediate and massive police and FBI response to secure the building and aid victims.

Rapid Onset of Violence and Immediate Police Response
Eyewitnesses described a barrage of bullets echoing through the lobby. The suspect, later identified as 27‑year‑old Shane Devon Tamura, emerged from a double‑parked BMW in body armor, wielding an AR‑style M4 rifle with high‑capacity magazines, then began firing indiscriminately—first striking off‑duty NYPD Officer Didarul Islam, who was serving as security in the building lobby.
Security staff and civilians attempted to flee or barricade themselves. A woman was allowed safe exit from the elevator by the shooter before he resumed firing near the elevators, killing a security guard and others before heading to the 33rd floor. The NYPD and federal agents arrived swiftly, locking down the scene, evacuating office workers, and searching the suspect’s vehicle, which contained additional firearms, ammunition, a rifle case, a backpack, and prescription medication.
Victims, Shooter, and Motive Under Investigation
The attack resulted in four fatalities, including Officer Didarul Islam—a 36‑year‑old Bangladeshi immigrant, father of two children with a third on the way—and two men and a woman. A fifth person remains hospitalized in critical but stable condition. The gunman died from a self‑inflicted gunshot wound inside an office on the 33rd floor of 345 Park Avenue.

Investigators revealed that Tamura had driven cross‑country from Las Vegas, passing through several states before arriving in New York on the day of the attack. He held a Nevada concealed carry permit issued in July 2022 and had a documented history of mental health issues. A suicide note found at the scene reportedly referenced anger toward the NFL’s handling of concussions and a personal struggle with mental health and CTE-like symptoms, though officials continue to validate the motive.
Heroism, Loss, and Citywide Reaction
Mayor Eric Adams and Police Commissioner Jessica Tisch praised Officer Islam for his bravery—describing him as a selfless hero who sacrificed his life while protecting others. Islam had served with the NYPD for over three years and leaves behind a young family.
Public officials, including Governor Kathy Hochul, expressed condolences to the victims’ families and reaffirmed their commitment to enhancing security protocols in major commercial buildings. Many companies in the building, including Blackstone, KPMG, and the NFL, released statements expressing grief and support for the injured and the bereaved families.
Building Impact and Broader Security Concerns
The violence in Midtown Manhattan—often considered one of the city’s most secure corporate hubs—has raised urgent questions about building security, active-shooter preparedness, and the vulnerability of high-traffic office towers. Businesses, tenants, and city leaders are now reevaluating emergency response drills and private security protocols to prevent future tragedies.
This attack further underscores concerns about public safety in urban business districts, reinforcing the need for preventive measures around gun access and mental health awareness.
