President Michel Temer signed the extradition of Italian Cesare Battisti on Friday afternoon, the Press Office of the Presidency of the Republic reported.
The former member of a leftist guerrilla group, Battisti was convicted in Italy of four murders committed in the 1970s.
On Thursday, Federal Supreme Court Minister Luiz Fux overturned an injunction granted last year to block Battisti’s extradition, ordered his arrest and said it was up to the president to decide on extradition.
According to a source of the Federal Police, Battisti is on the list of fugitives and Interpol has already been activated.
“We know he’s in São Paulo and there are a lot of operational teams and he’s on the lookout for him. We’re expecting him to get there,” said the source, who asked for anonymity.
