Despite threats to the Time Warner Center in New York, the CNN Center in Atlanta has not been targeted, police said Wednesday morning.

The Carter Center was also on alert and a spokesperson said the Carter family was also on the lookout, although nothing suspicious was reported. The GBI said bomb squads were not active Wednesday. And the FBI’s Atlanta office also said there was no indication of a threat.

According to various media reports, several suspicious packages believed to contain functioning explosives were intercepted in recent days. They were addressed to former President Barack Obama, former Secretary of State Hillary Clinton and the Time Warner Center in New York, where CNN films.

“The protectees did not receive the packages nor were they at risk of receiving them,” The Secret Service said in a press release. “The Secret Service has initiated a full scope criminal investigation that will leverage all available federal, state, and local resources to determine the source of the packages and identify those responsible.”

Atlanta police also reported no suspicious activity. But officers were prepared for the possibility, the agency said.

"We have alerted the beat officers where CNN and other television broadcasters are located to be watchful for suspicious activity,” APD said in an emailed statement.

The CNN Center was beefing up security at its entrances, according to company President Jeff Zucker.

“We are putting up magnetometers at the entrances to the building,” Zucker said in a memo posted on Twitter. “We remain vigilant regarding security concerns across all of our global locations.”
