A suspected Mexican drug trafficker wanted in the United States was arrested in Rio de Janeiro late Monday as he tried to board a plane to watch Mexico play in the World Cup, federal police said Tuesday. Federal police agents detained the unidentified man at Rio's international airport as he waited to board a plane to the northeastern city of Fortaleza. "He had tickets to go to the Brazil-Mexico game today," the police said in a statement, adding that the detained man is wanted for methamphetamine trafficking. Federal police said that the man was wanted by Interpol and was detected as soon as he crossed the border from Argentina on June 11. U.S. authorities were immediately alerted and have filed an extradition request, the police said.
