In September 2015, a bomb-making facility was discovered in a warehouse in Bahrain. Officers found chemical precursors and military-grade explosives.
They found armour-piercing projectiles that could slice its way through a tank and there were a large number of boxes of C-4 (military explosive).
Investigators in the country said that items like this had never been seen before there. In a report about the arsenals seized, investigators said that the firepower and caches found were a “game-changer”. The investigators also said that up against lightly armed police, the amount of arms seized was “overkill”.
