New York City, New York — An employee of the National Football League who survived the deadly Park Avenue office building shooting in July 2025 has filed a $24 million lawsuit against New York City, alleging that an off-duty police detective assigned to building security failed to prevent the gunman from entering the property.
The lawsuit, filed in Manhattan Supreme Court, was brought by Craig Clementi, who worked in the NFL’s finance department and was seriously injured during the attack.
According to court filings, Clementi alleges that the city’s negligence contributed to the mass shooting that claimed the lives of five people, including the detective, before the gunman died by suicide.
Lawsuit Alleges Gunman Entered Building Without Being Stopped
According to the complaint, 27-year-old Shane Tamura walked into the office building at 345 Park Avenue carrying an M4-style rifle before opening fire on July 28, 2025.
At the time, NYPD Detective Didarul Islam was working in uniform at the building through the department’s paid-detail security program.
The lawsuit alleges that the detective failed to recognize what it describes as an obvious security threat as the gunman crossed the plaza toward the building.
According to the filing, the suspect allegedly walked roughly 100 feet carrying the rifle in plain view before entering the lobby. The lawsuit argues that occupants inside the building were never warned before the shooting began.
Plaintiff Says He Was Seriously Injured During Attack
According to the lawsuit, Clementi was shot at close range in the side and lower back during the attack.
Despite suffering serious injuries, he alleges he managed to escape through a damaged revolving door before locating police officers nearby and calling 911.
Court documents state that he was transported to NewYork-Presbyterian/Weill Cornell Medical Center, where he underwent surgery to remove bullet fragments.
According to the filing, Clementi remained hospitalized for 10 days and later required home nursing care and physical therapy while recovering.
The lawsuit also alleges he continues to experience daily pain, permanent scarring and significant psychological trauma, including flashbacks and hypervigilance.
“I bear permanent depressed scars from the wound and I experience pain every day,” Clementi wrote in a court filing.
Detective Was Killed During the Shooting
Detective Didarul Islam, who was assigned to the 47th Precinct and participating in the NYPD’s paid-detail program at the time, was among those killed during the attack.
Following the shooting, NYPD Commissioner Jessica Tisch praised Islam, describing him as a dedicated officer, father of three and Bangladeshi immigrant who lost his life while serving.
The lawsuit argues that although Islam was working a paid security assignment, the city remains legally responsible because his law enforcement duties remained under municipal control.
Separate Lawsuits Also Expected
The Park Avenue shooting remains one of New York City’s deadliest recent workplace attacks.
Court records indicate the family of another victim, Julia Hyman, has also announced plans to pursue legal action against New York City over the shooting.
Authorities have said the gunman’s motive remains under investigation, although investigators believe he intended to target the NFL’s offices.
Following his death, investigators reported that Tamura left a suicide note referencing chronic traumatic encephalopathy (CTE). A postmortem examination later found diagnostic evidence of the degenerative brain disease.
The allegations contained in Clementi’s lawsuit represent the plaintiff’s claims. The city will have an opportunity to respond in court, and no judge has ruled on the merits of the case.
