SAO PAULO: Hundreds of supporters of Brazil’s former president Luiz Inacio Lula da Silva rallied outside his Sao Paulo house Saturday, a day after his dramatic detention in a corruption probe. The show of resolve was the latest sign a mounting political crisis over the investigation into alleged embezzlement and bribery at the state oil giant Petrobras was spilling onto the streets. “We are here out of solidarity,” said one man in the crowd, Jesualdo Freitas, 57. He described anger at Lula’s brief detention on Friday as having galvanized the left. “It strengthens the Workers’ Party and the movement to defend president Lula,” he told Agence France-Presse.
