Former Brazilian President Luiz Inacio Lula da Silva has been detained as part of a huge fraud inquiry into the state oil company Petrobras
Brazilian federal police said Friday they were carrying out 33 search warrants and 11 detention warrants in the Operation Carwash anti-graft investigation, including two in Sao Bernardo do Campo, the hometown of ex-President Luiz Inacio Lula da Silva, Reuters reports.
Local media reported that Lula was being brought in for questioning in the sweeping corruption investigation involving state-run oil company Petroleo Brasileiro SA.
The former president's house was raided by federal police agents and he was brought in for questioning.
Mr Lula, who left office in 2011, has denied allegations of corruption.
The long-running inquiry, known as Operation Car Wash, is probing accusations of corruption and money laundering at Petrobras.
Brazil's continuing corruption problem
Officials say some 33 search warrants and 11 detention warrants are being carried out by 200 federal police agents in the states of Rio de Janeiro, Sao Paulo and Bahia.
Mr Lula's house in Sao Bernardo do Campo, near Sao Paulo, was raided early on Friday. The headquarters of his institute in Sao Paulo was also targeted, as were his wife, Marisa, and sons, reports say.
