A former lawmaker in Thailand was arrested Monday for allegedly shooting a local government official and his driver, police said. Chalong Riewrang was arrested and taken to the local police station, Nonthaburi police chief Dejrapee Kongdee said. One of them, the chairman of the Nonthaburi local government administration, was "seriously injured," the police chief said. The presenter, former journalist Anchalee Paireerak, was seen reacting with shock and told him to wait for police to arrive. Officials have promised stricter gun laws since Friday's shooting, but previous pledges have failed to prevent repeated shootings.
