BRASILIA Aug 2 (Reuters) - Brazil's federal police on Tuesday arrested three people and raided properties as part of an investigation into alleged corruption at building firm Queiroz Galvao, a police spokesman said.
The investigation was part of "Operation Car Wash", the spokesman said, launched two years ago to tackle price-fixing, bribery and political kickbacks at state-run oil company Petrobras.
The police spokesman declined to name those arrested.
