MANHATTAN — The New York Time Warner building housing CNN was evacuated Thursday night after a 911 call was made for a suspicious package, but after about an hour officials determined the two unattended packages were safe.

The evacuation and call came just one day after a package containing a bomb, addressed to former CIA Director John Brennan, was found in the building.

"The NYPD Bomb Squad analyzed a couple of unattended packages inside the mall at 10 Columbus Cirlcle," the NYPD Midtown North account tweeted. "It was a false alarm. Continue to say something if you see something."

The NYPD bomb squad was on the scene, NYPD spokesman J. Peter Donald said.

The New York City Office of Emergency Management said to expect a heavy presence of emergency personnel near the building.

"Important to remember: NYPD wisely broadcasts these actions to manage confusion and unnecessary anxiety in the area," Eric Phillips, a spokesman for Mayor Bill de Blasio, tweeted. "We must all stay vigilant, while understanding that there will be a lot of these reports & precautionary episodes in the coming days. See something, Say something."

There's no confirmation yet on what the was in the unattended packages on Thursday night.
