Authorities in France said they are searching for a pair of bank robbers who escaped with only 50 euros, worth about $71. Police said the robbers, who wore ski masks, forced their way into the Credit Agricole bank in Nimes at 8:15 a.m. Wednesday and showed a knife to employees, Radio France Internationale reported Thursday. However, investigators said the robbers left with the small sum after finding out workers were not able to open any safes.
