TEHRAN, Young Journalists Club (YJC) - Christopher Ahn was arrested on Thursday and appeared on Friday in federal court in Los Angeles, according to a law enforcement official and a source close to the group.
In a related development, armed U.S. federal agents on Thursday raided the apartment of Adrian Hong, leader of Cheolima Civil Defense, a group seeking the overthrow of North Korean leader Kim Jong Un that is blamed for the Feb. 22 embassy raid, a person close to the group said without providing more details.
Hong was not present at his residence when the raid occurred, the source said.
The U.S. Justice Department declined to comment.
A group of at least 10 people stormed into the embassy, restrained and physically beat some personnel and held them hostage for hours before fleeing, according to a Spanish court.
Spanish investigators have said the intruders removed computers and hard drives from the embassy before fleeing to the United States, where they handed over the material to the FBI.
A Spanish judicial source said this week the material had been returned by Spanish authorities to Pyongyang's mission after being returned two weeks previously by the FBI to the Spanish court investigating the raid.
The anti-Kim group, which also calls itself Free Joseon, said the raid was not an attack and that it had been invited into the embassy.
