The Time Warner building, including the CNN's NY offices and studios were evacuated Thursday after receiving a phoned bomb threat.
The NYPD has confirmed that there is an ongoing investigation in the area and West 58th between 8th and 9th is closed.
Police are investigating a fake bomb threat at the building housing CNN's NY offices in Manhattan.
The bomb alert comes less than two months after CNN offices at the Time Warner Center were similarly evacuated due to what later turned out to be a pipe bomb, sent by Trump supporter Cesar Sayoc.
A police official said that an unsubstantiated phone threat was made to the Time Warner Building claiming there were five bombs present, and building security ordered an evacuation as a precaution.
CNN said several fire alarm bells signaling an evacuation rang inside its newsroom shortly after 10:30pm. CNN host Don Lemon tweeted, "We were evacuated in the middle of my live show" due to a bomb threat. The NYPD said they were investigating.
A bomb squad was on standby outside the building as police officers search the offices, a law enforcement source said. When programming returned, a taped version of Anderson 360 began broadcasting.
In October, Time Warner Center was evacuated after a package containing an explosive device addressed to ex-CIA Director John Brennan was discovered.
'FAKE NEWS - THE ENEMY OF THE PEOPLE, ' Trump tweeted just after 10pm.
