The CNN Center in New York was evacuated Thursday night after a phoned-in bomb threat.
The company said the call set off alarm bells inside the newsroom and studios.
Don Lemon’s "CNN Tonight" was taken off the air and replaced with taped programming as employees evacuated the building.
"We were told to evacuate the building and to do it as soon as possible. We grabbed what we could and got out of the building and now, we are standing outside of the building," Lemon said earlier, according to a CNN report on the incident.
No explosives were found.
In October, the network’s Time Warner Center was also evacuated after a package bomb addressed to former CIA director John Brennan was sent to the studios.
