Suspicious package at Marine Corps Base Quantico linked to Thanh Phan, FBI confirms

Authorities investigated a suspicious package that was spotted at the post office on Marine Corps Base Quantico on Thursday, according to federal authorities.

Officials at Marine Corps Base Quantico told FOX 5 a suspicious package arrived at the Quantico Post Office located at 400 5th St.

Investigators said they were expecting the package to arrive and said it was connected to 43-year-old Thanh Cong Phan of Everett, Washington, who was arrested for mailing several suspicious packages to military and federal institutions throughout the DC region.

The Marine Corps Base Quantico Explosive Ordnance Disposal responded to the post office at about 12:30 p.m. and gave the all clear at about 1 p.m., according to officials.

Marine Corps Base Quantico said the package was rendered safe and turned over to the FBI. There were no injuries or damage to property reported.

The FBI confirmed on Wednesday that Phan was now connected to packages being sent to at least 10 locations, including Fort Belvoir, Joint Base Anacostia-Boiling, Fort McNair, Naval Surface Warfare Center, Central Intelligence Agency, National Security Agency, Federal Bureau of Investigation, Mark Center Building, National Reconnaissance and a government mail facility in DC.

None of the packages that Phan allegedly mailed exploded or caused any injuries, officials said.

Federal authorities said they suspect more packages could have been mailed to processing facilities in the D.C. area. They are continuing to work to locate and isolate all of the packages.

Phan was arrested on Monday and has been charged with shipping explosive materials.
