An indigenous community in the Peruvian Amazon took at least eight public officials hostage to demand help from the central government after an oil spill polluted its lands, authorities said Monday.

The Wampis community of Mayuriaga seized a grounded military helicopter late on Sunday, holding crew members and several officials for their involvement in the emergency response plan, said German Velasquez, the president of state-owned energy company Petroperu.

A rupture in Petroperu's 40-year-old pipeline spilled 1,000 barrels of oil in Mayuriaga on Feb. 3, nine days after a leak in the same duct poured 2,000 barrels near eight other indigenous communities in the same Amazonian region.
