NEW YORK -- A freight building at John F. Kennedy Airport in Queens was evacuated Saturday afternoon after a screener found what appeared to be a grenade in a package on the premises, CBS New York reports.

The NYPD bomb squad was called to the scene at Building 77, a freight building. Authorities said it was determined the object found was an inactive training device being shipped for military training purposes.

Building 77 is not a terminal and there were no JFK passengers inside the building at the time.
