Two suspicious packages addressed to former Vice President Joe Biden were intercepted Thursday at separate postal facilities in Delaware, according to reports.

One package was found about 6 a.m. at the post office in New Castle, according to The News Journal of Wilmington, Del.

The second, also addressed to Biden, was found a short time later at the post office in Wilmington, about 7 miles north of New Castle, officials said.

A law enforcement source said the packages bore the same characteristics as those containing pipe bombs sent to other prominent Democrats and critics of President Trump.

It was unclear if Biden, whose spokesman Bill Russo referred questions to the FBI, was in Delaware or traveling Thursday, according to The Washington Post.

The package was apparently not delivered to Biden’s home and may have been on its way to being returned to the person listed on the return address, a source told the paper.

An FBI spokesman told The Post: “FBI Special Agents and local law enforcement are responding this morning to a United States Postal facility in Wilmington, Delaware to conduct law enforcement activity.”

The rep declined to provide further details about the investigation.

On Wednesday, federal law enforcement authorities investigating the possibility of an explosive device addressed to Biden swept his Delaware home but nothing was found.

The packages addressed to Biden were discovered as a device was removed from a Lower Manhattan property belonging to Robert De Niro.

Investigators could be seen early Thursday at the US Postal Service facility along Quigley Boulevard in New Castle, where the bomb squad deployed a robot.

Office workers at Avenue Medical Construction, which is located directly behind the post office, said they were evacuated from the building by police at about 6:45 a.m.

“It was quite an ordeal this morning. A little scary,” one employee, who did not want her name used, told The News Journal.

Her building’s heavy, steel loading door would protect them against a bomb, she said, but not the aluminum loading door. Looking at the post office, she said “normally this place is popping.”

At the Wilmington site, several neighbors and postal employees stood around outside the police tape at the closed-off Chestnut Street, where one woman told an arriving co-worker to “just go home.”

Other packages were mailed this week to offices and homes of prominent Democrats and public figures, including one sent to the CNN offices in Manhattan that was addressed to former CIA Director John Brennan.

Packages addressed to Hillary Clinton, former President Barack Obama, billionaire George Soros, ex-Attorney General Eric Holder and Rep. Maxine Waters all appear to have the same characteristics.

They contained the return address of the Florida office of Rep. Debbie Wasserman Schultz, the former chairwoman of the Democratic National Committee.
