They confirmed that ATO (Army Technical Officers) examined a suspicious object which had been discovered in the area and a number of items, including the BB gun, were removed for further examination.

BB guns are a type of air gun designed to fire spherical projectiles similar to shot pellets of approximately the same size.

Modern BB guns usually have a barrel with a bore and caliber of 4.5 mm (0.177 in) and are available in many varieties.

BB shot for modern BB guns is usually steel, plated either with zinc or copper to resist corrosion, and measure 4.3 to 4.4 mm (0.171 to 0.173 in) in diameter.

The term BB gun is often incorrectly used to describe a pellet or air gun. Although in many cases a BB steel ball can be fired in a pellet gun, pellets usually cannot be fired in a gun specifically designed for BBs. However, many air gun models using plastic ammunition allow for use of both types.
