Indigenous people living on Peru's largest oil field concession have seized some facilities operated by Frontera Energy Corp. demanding that the government apply an indigenous rights law before signing a new contract with the Canadian company, a tribal chieftain said on Tuesday.

The so-called prior consultation law, passed in 2011, requires the government to seek input from indigenous people before approving any development plans that might affect them.

Tribal chiefs in Frontera's Block 192 said the government has refused to carry out the consultation process even though it is negotiating a new contract with Frontera, whose two-year contract is due to expire this month.
