The New York Police Department said it is increasing its presence at “critical” locations across the city after receiving a vague bomb threat as officials prepare for the 24th anniversary of the Sept. 11 attacks, the United Nations General Assembly and the Jewish high holidays.

Commissioner Jessica Tisch told reporters the department was treating the information seriously even though the threats were unspecified and uncorroborated. She said the NYPD is working with federal partners through the Joint Terrorism Task Force and would surge resources at key facilities, including bridges and tunnels linking Queens and Manhattan.

The alleged threat, which sources told the New York Post had appeared on the radar of both the NYPD and the FBI, marked passages between Manhattan and Queens as potential targets for an unspecified “group.” Those sources said possible ties to Iran were suggested, but Norton police and federal officials described the reporting as lacking specifics about timing or methods.

"As always, we take all threats seriously, and we are working with our federal partners through our Joint Terrorism Task Force, as we investigate," Tisch said. "Out of an abundance of caution, we are surging resources, and you can expect to see an increased police presence at critical infrastructure locations." She added that threats typically increase during the busy weeks surrounding the 9/11 anniversary, the UNGA and the Jewish high holidays.

An NYPD spokesman described the recent intelligence as "unspecified, uncorroborated threats" that nonetheless warranted heightened vigilance. The department did not release details about operational changes or the precise locations that would see augmented patrols, citing ongoing investigative work.

Officials framed the move as part of a broader push to reassure residents and visitors during a period when the city draws large crowds and international delegations. The United Nations General Assembly brings foreign leaders and large entourages to Manhattan each year, and the 9/11 anniversary routinely draws memorial events and heavy public attendance at lower Manhattan sites.

Security concerns in New York City have been intensified by several high-profile incidents this summer. In July, a gunman opened fire at an office tower on Park Avenue, in what authorities called the city's deadliest shooting in decades. The attack prompted renewed scrutiny of building security and workplace violence prevention. Earlier this month, Times Square was briefly shut down after a suspicious package was left near a small NYPD post; the suspect was arrested and later underwent a psychiatric evaluation. New York's Immigration and Customs Enforcement field office was also evacuated after five envelopes containing a white powder were found in a mail room; testing later identified the substance as boric acid.

Those episodes, coupled with the forthcoming commemorations and international meetings, have contributed to an atmosphere in which law enforcement officials say they must adopt layered security measures. Federal, state and local agencies typically coordinate planning for the UNGA and major anniversaries through intelligence-sharing and operational briefings in the weeks leading up to the events.

City officials did not advise changes to public transit or closures of major crossings but urged New Yorkers to remain alert and report suspicious activity. Police said the visible surge in personnel and patrols is intended both to disrupt potential plots and to provide reassurance to the public.

Investigations into the recent reports are ongoing. Authorities emphasized that vague or uncorroborated threats require careful assessment and interagency cooperation to determine credibility and, if warranted, to identify and interdict suspects before they can act.
