Athens (CNN) -- Robbers broke into a museum in Olympia, the birthplace of the Olympics, tied and gagged a museum guard, and fled with stolen artifacts, Greek authorities said Friday. The two men raided the Museum of the History of the Olympic Games, a smaller building close to the main Archaeological Museum of Olympia, just after 7:30 a.m. local time, said Athanassios Kokkalakis, a police spokesman. The robbers "approached the museum's guard, tied her hands and bound her mouth and then went into the museum, where they took 65 to 68 small clay and brass small statues, and a gold ring, and put them in a bag and left."
