Police said that a man has been detained after a minor explosion in a hotel in downtown Copenhagen. Police spokesman Henrik Moeller Jacobsen says the man had slight injuries on his face and arms, and was arrested in a park near the blast site, according to AP. The cause of the explosion was still being investigated. Danish tabloid Ekstra Bladet says the man is from Luxembourg, but Moeller Jacobsen could not confirm that information. Moeller Jacobsen says the «small explosion» occurred 1139 GMT Friday in a bathroom of the Hotel Joergensen. The low-cost hotel is located about 100 yards (91 meters) from Copenhagen's busiest commuter and regional train station.
