CNN's New York studio was evacuated Thursday night in the middle of a live programme following a phoned-in bomb threat, according to the news network. The threat came Thursday night when a caller indicated there were five devices in the building, according to a law enforcement source.

Several fire alarm bells rang inside CNN's New York newsroom, signalling an evacuation after the call was received shortly before 10 pm, the company's security said. Staffers evacuated the CNN New York offices in the Time Warner Center building and Don Lemon's "CNN Tonight," which had been on a commercial break, was taken off the air. The network temporarily went to taped programming for about half hour before going live from the street while police investigated.
