A South Korean court on Thursday denied a special prosecutor clearance to arrest the head of Samsung Group [SAGR.UL], the country's largest conglomerate, amid a graft scandal that has led to the impeachment of President Park Geun-hye. The pre-dawn decision by the Seoul Central District Court to allow him to go home was welcomed by Samsung Group. The 48-year-old left the Seoul Detention Centre carrying a white shopping bag and climbed into a car without talking to reporters, having been held overnight as the court deliberated whether to grant the arrest warrant.
