Police swooped on four men suspected of being arms sellers and who are now being held behind bars. The men, who were known as military arms and history enthusiasts, were from the Pardubice and South Moravia regions. Searches uncovered rifles, pistols and machine guns as well as explosives and ammunition. Police from the special unit for combatting organised crime said part of the men’s business appeared to be importing damaged guns, repairing them, and then selling them on abroad. They could face up to eight years in prison for illegal possession of and trade in arms.
