HEBRON, Ky. -- A hand grenade in a passenger's carry-on bag has caused a temporary evacuation at the northern Kentucky airport.

The Delta Air Lines terminal at Cincinnati/Northern Kentucky International was cleared for about 10 minutes Tuesday night after the device was found at about 7:30 during routine baggage screening.

The passenger who carried it was denied boarding and the grenade was confiscated. No flights were canceled or delayed.

The passenger was released, but is now under investigation by the TSA.
