Rio de Janeiro ( CNN ) -- As Brazilian authorities work to `` pacify '' Brazil 's slums ahead of two global sporting events , police in Rio de Janeiro captured one of the city 's most notorious drug traffickers . Antonio Francisco Bonfim Lopes , alias `` Nem , '' was found hiding Wednesday in the trunk of a car attempting to avoid a police siege in the outskirts of Rocinha , a slum in the heart of Rio that was under his control , police said . But the car was stopped at a police checkpoint , and a confusing scene unfolded . The driver of the car told police he was a Congolese diplomat and refused to open the trunk , police said . He then partly relented , saying he would only open it at the federal police station . On the way there , police said , the car stopped again and one of its occupants offered the officers 20,000 reais ( U.S. $ 11,400 ) in exchange for their freedom . When the officer declined , the offer was raised to 1 million reais ( U.S. $ 572,000 ) , police said . The local officers called in federal police , who conducted an immediate search of the vehicle and discovered Lopes in the trunk , police said . The driver claimed to be an `` honorary consul '' of `` Congo , '' but the embassy of the Republic of Congo told the state-run Agencia Brasil that they have no consul in the country , and the Democratic Republic of Congo said it has no diplomatic mission there . A second passenger in the car was identified as an attorney and a third man also claimed to be an employee of the consulate . Rio will play host to the 2014 World Cup and 2016 Olympics , and has turned its attention to restoring control of the slums , or favelas , that had been in the hands of criminals and gangs . Rocinha is one of Brazil 's biggest favelas and one of the main strongholds of the drug dealing in the country . Rocinha is a community with nearly 70,000 residents , according to the last census . Lopes controlled the drug trafficking in that favelas for nearly 10 years .
