Two of the four were arrested in the Thai capital and two in the southern province of Yala on suspicion of selling a modified blank gun to the 14-year-old, who has been charged with premeditated murder and illegal possession of a firearm. Mass shootings are rare in Thailand, but gun violence and gun ownership is common. "The digital ministry will be shutting down websites selling blank guns," Jakkapong Sangmanee, the deputy foreign minister, told a separate briefing. The government plans to ban imports of blank guns, BB guns and imitation firearms, its deputy spokesperson, Karom Phonphonklang, said in a statement.
