Rio de Janiero, Brazil ? Cracking down on visitors who come to Brazil for sex, police raided clubs known for using call girls and strippers, detaining 118 foreigners early Saturday to discourage what authorities called “sexual tourism.”

The tourists – mostly from Portugal, Spain, Italy, France and Norway – were briefly held in the northeastern city of Natal for not carrying passports or international identification cards that Brazil requires of all foreigners, police said. They were fined $76 and released.

Luiz Pereira, a federal police officer, said the country hoped the operation “will help discourage tourists who think sexual tourism is easy in Brazil.”

More than 70 federal agents raided two nightclubs known for using strippers and call girls to attract tourists, Pereira said.

Prostitution is legal in Brazil, but people who promote sex tourism can be charged.
