A judge in Sao Paulo transferred on Monday pending charges against former President Luiz Inacio Lula da Silva to the federal court in Curitiba, citing an "undeniable connection" to a broad investigation into kickbacks at state-run oil firm Petrobras, according to Reuters. State prosecutors in Sao Paulo asked for an arrest warrant for Lula last week after charging him with money laundering and identity fraud for concealing ownership of a beach front apartment, a process that was previously separate from the vast corruption probe Judge Sergio Moro oversees in southern Brazil city of Curitiba.
