NBC4 New York is reporting that an “all-clear” has been given after a suspicious package prompted an evacuation of LaGuardia Airport’s central terminal.

The package was found near a phone booth and had protruding wires, WABC sources described.

CNBC tweeted: “According to Port Authority Public Affairs, the suspicious package at LaGuardia turned out to be a lighting ballast with wires sticking out.”
