As of now, all FBI agents have left the residence, the correspondent added.
It is unknown what is in the boxes that are being carried out of the house, which allegedly belongs to Deripaska's relatives.
FBI also confirmed to Sputnik it was conducting authorized law enforcement activity at a property in Washington, supposedly linked to Deripaska. The house was taped off with the tape saying "CRIME SCENE DO NOT ENTER."
The Sputnik correspondent witnessed a large van earlier accompanied by cars with flashing lights that left the territory in the area of 12 Gay Street in Manhattan. The authorities closed the street at the time.
A Deripaska representative told Sputnik that the FBI was conducting searches at the homes of his relatives in Washington and New York in connection with the US sanctions regime. Prior to that, The Washington Post reported that the officers had conducted searches as part of an unspecified criminal investigation into the activities of a man who has not been to the United States for several years.
The FBI and the US Justice Department have declined to comment on the details of the probe.
