Brazilian police on Friday arrested the CEO of Grupo Galvão, the latest executive seized in a corruption probe focused on state-run oil firm Petroleo Brasileiro SA. Dario Galvão, chief executive of the construction group, and Guilherme Esteves, a lobbyist who is being investigated for funneling bribe money, were taken to federal police headquarters in the southern city of Curitiba, a court spokeswoman said. Trials are underway in Curitiba, in what has become Brazil’s biggest-ever corruption probe known as Operation Car Wash.
