LA PAZ/SANTA CRUZ, Bolivia, Dec 28 (Reuters) - Bolivian police on Wednesday detained Luis Fernando Camacho, the governor of Santa Cruz and a prominent opposition leader, the latest sign of political tensions in a region that saw the arrest of a president in neighboring Peru earlier this month. Authorities have not said why Camacho was arrested but he recently helped lead weeks of protests that blocked streets and halted trade in Santa Cruz. Camacho was taken to a local airport to be flown to La Paz, local media reported. "The operation to kidnap the governor was carried out in the streets near his home, as he was returning from his duties," the Santa Cruz government said in a statement. Opposition Senator Erik Moron said in a video that he had been taken by helicopter to an unknown location.
