Third Bomb Threat Shakes Nantucket's Main Street, FBI Joins Investigation
August 11, 2025
On the night of the latest threat, an individual claimed they intended to place an improvised explosive device (IED) at the location, prompting a swift response from the Massachusetts Bomb Squad, which was already on the island for a separate event.
Despite the chaos, police have not yet identified a suspect or motive for the threats, although multiple businesses in the area were affected by the evacuations.
Local businesses, including the Ralph Lauren store, were evacuated during the incidents, but staff declined to comment on the impact on business during the tax-free weekend.
Nantucket Police are currently investigating a third bomb threat at 16 Main St., reported just before 10:30 p.m. on August 9, 2025.
In response to the threat, first responders quickly established a cordon and evacuated non-essential personnel from the area to ensure safety.
The area was declared safe by 1:09 a.m. on August 9, after the Bomb Squad completed their search.
The bomb threats have sparked widespread discussion among island residents, raising concerns about safety and the impact on local businesses.
Authorities are urging anyone with information regarding the bomb threats to come forward to assist in identifying those responsible and ensuring public safety.
As the investigation continues, the FBI has joined local law enforcement, but no suspects or leads have been identified yet.
This story is still developing, with updates expected as more information becomes available.
Previous bomb threats at the same location concluded without finding any explosives, and the Nantucket Police Department emphasized the seriousness of all threats, thanking the public for their cooperation.
The report indicated that the individual who reported the IED was armed, leading to a coordinated response from the Nantucket Police Department, Massachusetts State Police, and Nantucket Fire Department.
