Former Brazilian President Michel Temer has been arrested in São Paulo as part of a massive corruption investigation.
Mr Temer was arrested in his hometown of São Paulo on Thursday morning local time and will be flown to Rio de Janeiro.
Local media say police had been trying to trace Mr Temer since Wednesday. His former Mining and Energy Minister Moreira Franco was also arrested.
The corruption scandal involves millions of dollars in kickbacks and more than 80 politicians and members of the business elite. It provoked huge street protests nationwide.
Operation Car Wash's most high-profile conviction is of former leftist President Luiz Inácio Lula da Silva, who is now serving 12 years in jail for corruption.
