Washington: US authorities have arrested a former marine in connection with a mysterious February raid on North Korea’s embassy in Spain during which masked assailants roughed-up staff and stole computers, the Washington Post reported Saturday. Citing two sources familiar with the case, the Post said federal authorities arrested Christopher Ahn, a former US Marine and member of a group dedicated to the overthrow of North Korean leader Kim Jong Un. An FBI spokesman referred questions on the case to the Justice Department, who declined to comment. (AFP)
