Cases on nine individuals from three North Korean human rights groups have been sent to the prosecutors’ office, the Seoul Metropolitan Police Agency confirmed to NK News on Thursday. Sources say that they have been accused of breaking an inter-Korean exchange law by sending balloons filled with bibles or anti-DPRK leaflets across the border.

Eric Foley, the CEO of Voice of the Martyrs Korea (VOMK), Park Sang-hak, the head of Fighters for a Free North Korea (FFNK) and Park Jung-oh, the head of Kuensaem, told NK News that their groups were the three included in that list. The police have concluded their investigation and the prosecutors’ office will now decide if their cases will be taken to the court or not.
