A member of the anti-North Korea extremist group Free Joseon that raided the North Korean embassy in Madrid, Spain, has been arrested in the US by the FBI. The FBI arrested former US marine Christopher Ahn in Los Angeles on Apr. 19, according to an AP report on Apr. 21. The AP added that US federal agents raided the home of Adrian Hong, another Free Joseon member, on Apr. 18, but Hong was not in his residence during the raid. The arrest of Ahn is significant as it comes at a time when North Korea and the US are in negotiations for a third summit. The photo shows Free Joseon’s objection to the arrest on its website.
