An explosive device was found Thursday at actor Robert De Niro’s production offices.

Security staff at TriBeCa Productions called the New York Police Department about a suspicious package; X-rays detected the contents were explosive.

The device was reportedly similar to ones recently sent to former President Barack Obama, Secretary of State Hillary Clinton, and others.

The investigation to find the person or persons who has sent these packages has widened to the New York, Washington, Florida, and Los Angeles areas.

De Niro has been one of Hollywood’s most outspoken critics of President Donald Trump. He’s merely the latest to be targeted with an explosive device.

Others sent suspicious packages include Democrat donor George Soros, former CIA Director John O. Brennan, Obama, former President Bill Clinton, and Reps. Maxine Waters (D-Calif.) and Debbie Wasserman Schultz (D-Fla.).

CNN’s New York bureau in midtown Manhattan was also reportedly sent a package.

De Niro has gone on several vulgar rants criticizing the president in the past.

Trump bit back at the actor over the summer, saying on Twitter, “Robert De Niro, a very low IQ individual, has received too many shots to the head by real boxers in movies. I watched him last night and truly believe he may be ‘punch-drunk.’ I guess he doesn’t realize the economy is the best it’s ever been with employment being at an all-time high, and many companies pouring back into our country. Wake up, Punchy!”

De Niro, meanwhile, has said he wants to “punch” Trump “in the face” and even announced he wouldn’t let the president eat at a Japanese restaurant he was helping to open.

He also said Trump “believes he can make up his own truth.”

The “Goodfellas” and “Taxi Driver” actor also appeared on “Saturday Night Live” as Robert Mueller not long ago — and said he fantasized about reprising the role and hauling of Trump off to jail in a scene.

“I hope there’s a couple [of segments] where I interrogate [Trump], I arrest him, and then I take him to jail,” the actor said.

The president has called the sending of explosive devices to political figures an “attack on our democracy” and “abhorrent.”

De Niro, 75, has been nominated for seven Academy Awards and has won two. He won the Best Supporting Actor Academy Award for 1974’s “The Godfather: Part II” and the Best Actor trophy for 1980’s “Raging Bull.”

De Niro can next be seen in “The Irishman,” a gangster-themed picture that finds him reuniting with director Martin Scorsese and actor Joe Pesci. The three previously made the films “Goodfellas” and “Casino” together.

He also has a role in the upcoming film “Joker,” which will hit theaters next October.
