Police were called to the Time Warner Center in New York on Wednesday to investigate a suspicious package that forced employees from CNN and other companies to evacuate for several hours.

CNN temporarily cut a live broadcast out of its New York City studios, which are housed in the building, after an alarm went off amid the evacuation.

Anchors Poppy Harlow and Jim Sciutto later continued to broadcast from the street on their cell phones after being evacuated from the studio.

ADVERTISEMENT CNN President Jeff Zucker said in a note to employees in New York that the building was evacuated "out of an abundance of caution," saying a suspicious package had been received in the mailroom.

The building was reopened after the New York Police Department finished a security sweep, Zucker announced in a memo sent around 3:30 p.m.

Zucker had said in an earlier memo that the network was also "checking all bureaus around the world, out of a complete abundance of caution."
