GENEVA (AP) — Swiss authorities are searching for two robbers who overpowered a security guard at an ancient Rome-themed museum in Lausanne, smashed a display case and made off with dozens of gold coins that had been displayed inside. City police said late Thursday that the suspects had purchased tickets and waited until other visitors had left shortly before closing time before assaulting and restraining the guard, then breaking the display case. The monetary value of the loot was not immediately revealed but police said the coins had “archaeological value.” Officials said the Lausanne museum employee, a 64-year-old Swiss national, was interviewed by investigators and that he was not injured in the incident.
