The Transportation Security Administration says it stopped a Virginia man from bringing a live smoke grenade on a flight at Dulles International Airport.

The TSA says the Great Falls resident was not charged and was allowed to continue on his flight to Denver. The device was confiscated.

The smoke grenade was concealed under the inner lining of the man's carry-on bag. Smoke grenades and stun guns are among the weapons prohibited in carry-on baggage.

The grenades are used to create smoke screens, allowing people to move while under fire. They are sometimes used in paintball games.
