BRASILIA - Brazilian authorities moved Monday to upgrade security at government buildings ransacked by rioters, and formally charged 39 people with crimes against the state in the violent 8 January uprising.
Leao is standing in for Ibaneis Rocha, who is the target of an investigation into possible links to the riots and was relieved of his duties for 90 days. Leftist new President Luiz Inacio Lula da Silva and his justice minister have both said the unrest could not likely have happened without inside help, including from the security forces.
According to the Federal Police, 1,159 people out of more than 2,000 suspected rioters initially detained remained under arrest.
