Various police forces have collaborated to crack down on a group suspected of staging armed robberies with AK rifles in at least four provinces, officials said Monday. The arrests occurred last week following a tip from residents of Kampong Speu’s Treng Troyoeung village, who reported seeing 12 people armed with rifles and grenades and speculated that they were about to rob a local market. Police officers exchanged fire with the group and managed to wound a man suspected of being its mastermind. Police initially arrested three men, including the injured leader. Tips from those arrested men then led them to four other men. Police are now looking for five remaining suspects.
