Brass knuckles, toy guns, even a grenade are just some of the items TSA has stopped at JIA

The Transportation Security Administration said it's stopped 2,800 pounds of prohibited items from getting through the security checkpoint at Jacksonville International Airport.

People have packed bizarre and even potentially dangerous items in their carry-on bags, including brass knuckles, toy guns and a grenade.

Even though it didn’t have explosives, it could have caused an evacuation at the checkpoint and a lot of angry passengers who may have missed their flights.

TSA does hold the nonprohibited items at the airport for about 30 days, to allow passengers to recover them.
