Sao Paulo , Brazil ( CNN ) -- A female foreign tourist was kidnapped , raped and robbed on a minibus in Rio de Janeiro , police said , highlighting security concerns in the Brazilian city that will host matches in the 2014 World Cup and will put on the Summer Olympics two years later . A male foreign tourist on the minibus was also held captive and robbed , according to Rio police . Police said they would not release the identities or nationalities of the victims , but the U.S. Embassy said Monday that one of the two is an American citizen , and a U.S. State Department official on Monday said the woman raped was a U.S. citizen . The U.S. Consulate is in contact with the victim and is providing all appropriate consular assistance , said the State Department official , who did not want to be identified because he was not authorized to talk about the case . In general , consular assistance includes ensuring access to medical care , working closely with law enforcement authorities , assisting in understanding the local criminal justice process , and following any criminal proceedings very closely , the official said . The consulate also communicates with family members in the United States , and helps provide U.S.-based resources for the victim when possible , the official said . The two boarded the minibus in the Copacabana beach district in Rio de Janeiro early Saturday . Three men subsequently boarded the minibus and forced all the other passengers off , police said . The woman was raped , and the two passengers ' credit cards were used at multiple locations inside and outside of Rio de Janeiro over a span of hours , the police said in a statement . According to Brazilian newspapers , the man was handcuffed and beaten , while the woman was repeatedly raped . The two were dumped in Itaborai , a city more than 30 miles ( about 50 kilometers ) away , after six hours , O Globo newspaper said . According to Rio police , two men have been arrested -- Jonathan Foudakis de Souza , 20 , and Wallace Aparecido Souza Silva , 22 . They are searching for a third man in relation to the crime . They said a Brazilian woman who was raped a week earlier has also identified the suspects . Rio de Janeiro has launched a citywide offensive against crime , particularly drug-fueled violence in the shantytowns . Police , backed by army troops , have stormed the slums , hoping to seize control from gangs and help secure the city before many high-profile events begin this year . Pope Francis ' first big international trip will be to Rio in July when he is expected to lead millions of young people in celebration of World Youth Day . Rio de Janeiro also will stage many of the key matches when Brazil hosts the World Cup next year , and it will be the host city for the Olympic Games in 2016 . Rio has gone a long way toward cleaning up its image as one of Latin America 's most violent cities . But Brazilian media already are drawing parallels between this attack and the infamous gang rape of a young woman on a bus in India .
