All you might feel is someone brush by you and a slight pin prick . But very quickly you would be suffering muscle paralysis followed by suffocation . You would be dead within a very short period of time . This is the deadly effect of just one of the weapons found on a failed North Korean assassin last year on the busy streets of Seoul , now shown exclusively to CNN . Disguised to look like a Parker ballpoint pen , it contains a poison needle and is practically impossible to identify as a weapon . The second pen shoots a poison-filled bullet which penetrates the skin and releases the toxin and the third weapon is a flashlight , loaded with up to three bullets . They all look completely innocuous but all three will kill . An individual willing to be identified only as an `` investigation official '' showed CNN the weapons , pointing out the flashlight as the most significant find . `` This flashlight is new , '' the man familiar with North Korean assassination devices said . `` I 've never seen this weapon . If you look at the front , there are three holes , there was a bullet in each hole and here is the trigger . This is currently loaded and dangerous , two bullets remain . '' The third bullet had been fired by investigation authorities to test the weapon . It was accurate and deadly . The would-be assassin who was carrying these devices was arrested on his way to kill his target . That target was anti-North Korea activist , Park Sang-hak , who has since been given round-the-clock police protection by South Korean authorities . We showed Park the footage of the weapons intended for him . He was shocked . `` You 'd notice a gun , but these weapons are so innocuous , you can easily kill someone , I 'd be dead immediately . '' Park says he will continue to send anti-Pyongyang propaganda leaflets across the border in balloons , a practice which has angered the regime , sparking threats of military retaliation . He was aware he was at the top of North Korea 's hit list . Park had been in contact with the would-be assassin , named only as Ahn , as Ahn had expressed interest in funding his activism . He was on his way to meet him when the National Intelligence Service intervened and stopped him . It was at that meeting Ahn was believed to have planned to kill Park , according to South Korean authorities . Ahn was convicted in April and sentenced to four years in prison . `` I did n't believe they 'd try and kill me on the crowded streets of Seoul , I thought the NIS was over-reacting , '' Park said . He now knows they saved his life but is also convinced that it will not be the last attempt on his life .
