The New York Police Department revealed Wednesday that no device was found at the Manhattan office of New York Gov. Andrew Cuomo, saying a suspicious package found there was cleared and "unrelated."

"The earlier suspicious package at Governor Cuomo’s office in midtown has been cleared by NYPD personnel. It was unrelated. And there was no device of any kind," said J. Peter Donald, a spokesperson for the NYPD, in a tweet.

A preliminary investigation found that the package contained computer files on a "hate group," the Proud Boys, who recently made an appearance in New York, said Rich Azzopardi, a spokesman for the governor's office.

Cuomo had said at a press conference earlier Wednesday that there was a device sent to his Manhattan office after the Secret Service announced that explosive devices had been sent to former President Barack Obama, former President Bill Clinton and former Secretary of State Hillary Clinton. The governor had said the situation was "being handled" by authorities.

"As you've heard, there is a number of devices, and there's a pattern apparently to the number of devices. We wouldn't be at all surprised if more devices show up," Cuomo said. "A device has been sent to my office in Manhattan, which we were just informed about, and that device is also being handled.

"Again, this is a situation," he added. "A number of devices have been sent. They're being handled. We wouldn't be surprised if additional devices are sent, and the device that has been sent to my office has been identified and is being handled as we speak."

Earlier in the day, Azzopardi said that initial reports of a device found were "untrue." He tweeted after the governor's announcement during the press conference that a package was discovered after the initial comment.

Along with Obama and the Clintons, suspicious packages were also addressed to former Attorney General Eric Holder and former CIA chief John Brennan, which ended up at CNN's offices in New York.
