In November 2012 tensions mounted when federal police in the region shot dead the Indian Adenilson Munduruku . On 3 April 2013 the Federal Public Ministry ( MPF ) asked for the federal government to suspend a military/police operation that was underway in the Tapajós region and to suspend studies and licensing for the São Luiz do Tapajós plant . The police and military were protecting a team of 24 researchers in the area , with more due to arrive . The MPF asked that the Munduruku Indians and the directly affected '' ribeirinhos '' communities first be consulted , as required by the International Labor Organization 's Indigenous and Tribal Peoples Convention , 1989 , to which Brazil subscribed in 2002 . The MPF stated that the armed operation violated human rights , prevented any chance of dialog in good faith and would tend to create confrontation . On 16 April 2013 the Federal Regional Court of the 1st Region ( TRF-1 ) in Brasilia ordered that the government suspend the military and police " Operation Tapajós " in the region of the Mundurucu Indigenous Territory
