Transportation Security Administration officials confiscated a ceramic grenade at Honolulu International Airport this week, according to the TSA Blog.
Honolulu was one of 10 U.S. cities this week that TSA workers found grenades that were live, inert, novelty or replica grenades in carry-on bags.
Another four grenades were found in checked bags at Akron Canton, Las Vegas, Washington Dulles and San Jose.
An inert grenade was confiscated at Honolulu International Airport back in May. A gearshift grenade and a ceramic grenade were also confiscated at the same airport back in February.
The TSA would like to remind traveling that any item that looks like a grenade, bomb or mine is prohibited, whether it is real or not.
When these items are found at a checkpoint or in check baggage, they can cause significant delays in checkpoint screening.
