Just for the record, an ex marine has been arrested allegedly in connection with this incident.Last month the North Korean embassy in Spain was raided by a mysterious group who claim to wish to overthrow the government of North Korea. They tied up the embassy staff, allegedly tortured them, and made off with computer hard drives and secret documents.
North Korea calls raid on Madrid embassy 'grave terrorist attack' | CBC News
North Korea are demanding an investigation into it, calling it a "grave terrorist attack" and a violation of international law.
The Spanish are apparently doing some sort of investigation, but the details are still under wraps.
The Americans identified the group as "Cheollima Civil Defence".
The BBC have more information on them. The Spanish say they were armed with machetes, knives, and metal bars. The information taken was then handed over to the US.
Who was behind North Korean embassy raid?
The group apparently has a web site and a Youtube channel. I'm not about to visit either.
One of the known members is someone based in the US. According to the Spanish he was the ringleader of the raid on the Madrid embassy.
The Spanish press report that the group has links to the American CIA.
