A grenade was discovered inside a trash can near the federal building in Downtown Pittsburgh on Monday morning, prompting a response from the Pittsburgh Police Explosive Ordnance Disposal unit in the 1000 block of Liberty Avenue. Public safety officials believe the device is likely inert, but they are still working to verify that before closing out the investigation.
The EOD unit removed the grenade and took it to the city's firing range, according to WPXI, whose reporter Jess Shannon first reported the discovery. Pittsburgh police are assisting the Department of Homeland Security in the investigation, a partnership that reflects the location's federal footprint. The 1000 block of Liberty Avenue is dominated by the William S. Moorhead Federal Building, a 23-story, 340-foot skyscraper managed by the General Services Administration, according to Wikipedia.
Why Federal Agents Got Involved
The Department of Homeland Security's Federal Protective Service is authorized under 40 U.S.C. § 1315 as the primary federal law enforcement agency responsible for investigating security threats and protecting federal property nationwide, per Homeland Security. The agency oversees law enforcement services across roughly 9,000 federal facilities, which explains why FPS is working the case alongside Pittsburgh police rather than the city handling it alone. Homeland Security regulations also direct federal building occupants and visitors to promptly report suspicious packages or unusual circumstances on federal property to the FPS MegaCenter, a centralized dispatch hub for FPS officers.
The building at the center of the response is no minor office annex. It houses dozens of government entities, including the U.S. Army Corps of Engineers Pittsburgh District, the U.S. Equal Employment Opportunity Commission's Pittsburgh Area Office, the VA Regional Office, and the Department of Housing and Urban Development field office, according to the U.S. Equal Employment Opportunity Commission. Those offices host hundreds of employees and members of the public on any given day, adding urgency to confirming what kind of device turned up just outside.
A History Tied To The Site
Built in 1964 to consolidate 21 scattered federal offices in Pittsburgh, the 770,000-square-foot Moorhead Federal Building has since undergone major modernizations by the General Services Administration aimed at improving security and energy efficiency for its roughly 50 tenant agencies, per PageThink. The tower was constructed on the site of a former Greyhound bus terminal. For several decades after the building opened in November 1964, the FBI's Pittsburgh Field Office was headquartered on its 13th floor, handling national security and federal investigations from that location, according to the FBI.
This is not the first security scare tied to the address. Law enforcement previously investigated a reported bomb threat at the Moorhead Federal Building in February 2021, according to CBS Pittsburgh, underscoring that federal buildings like this one operate under heightened security protocols whenever a threat surfaces.
A Familiar Pattern For Pittsburgh's Bomb Squad
Monday's discovery echoes a similar call the city's EOD unit fielded earlier this year. On April 8, 2026, Pittsburgh police and the bomb squad responded to the 500 block of East Ohio Street on the North Side after an inert training grenade was found on a porch, an incident Hoodline previously covered. That call prompted street evacuations before technicians confirmed the device lacked explosive powder, even though its outer metal shell closely resembled a live weapon.
The region has seen other ordnance scares as well. In November 2024, a West Virginia man was charged after bringing a live flash-bang grenade into security screening at Pittsburgh International Airport, requiring EOD technicians to secure the site. Whatever the outcome of Monday's testing, city rules are clear that hazardous or explosive materials are not permitted in public trash cans or curbside pickup bins; Pittsburgh's Environmental Services department requires special drop-off or law enforcement handling for such items, according to the City of Pittsburgh. How the grenade ended up in a Downtown trash can remains unclear, and officials have not said whether they suspect it was intentionally placed, improperly discarded as a souvenir, or left behind as an inert training casing.
