The package arrived at the building in Tribeca in Lower Manhattan that houses Mr. De Niro’s production company and restaurant. It was similar to those discovered a day earlier and was also believed to contain an explosive device, officials said.

On Wednesday, in the center of Manhattan, the Time Warner Center, an elegant office and shopping complex, was evacuated because of a pipe bomb sent to CNN, which has its New York offices there. It was addressed to John O. Brennan, a critic of Mr. Trump who served as Mr. Obama’s C.I.A. director.

None of the devices harmed anyone, and it was not immediately clear whether any of them could have. One law enforcement official said investigators were examining the possibility that they were hoax devices that were constructed to look like bombs but would not have exploded.

The F.B.I. said the devices were similar to one found Monday at the home of George Soros, the billionaire philanthropist and liberal donor, in a New York City suburb.
