Five more men have been arrested in an investigation into the murder of British journalist Dom Phillips and indigenous expert Bruno Pereira in the Amazon rainforest.
Brasilian police said in a statement that seven arrest warrants were issued for illegal fishing in the Vale do Javari region, the remote area close to the border with Colombia and Peru where Phillips and Pereira disappeared on June 5.
The region has been invaded by illegal fishermen, loggers and gold miners, while police say it is a key drug trafficking route.
Phillips, a freelance reporter who had written for the Guardian and the Washington Post, was doing research for a book on the trip with Pereira.
Two of the seven suspects were already under arrest: Ruben Dario da Silva Villar, known as "Colombia", and fisherman Amarildo Costa de Oliveira, known as "Pelado" who was arrested in June as the primary suspect in the murder.
According to the police, Colombia would be the leader and financier of an armed criminal gang involved in illegal fishing that was smuggled out to the neighbouring countries.
Three of the newly arrested men, whose names were not revealed, are relatives of Amarildo and were involved in concealing the bodies of Phillips and Pereira, the police said.
Pereira, the former senior official at the federal indigenous affairs agency Funai, had previously clashed with
Amarildo over illegal fishing within the indigenous territory.
Federal prosecutors said that Phillips was killed so that he could not identify the killers.
