Police use tear gas on protesters angered after Brazil's ex-president, who is facing corruption charges, is sworn in as chief of staff to the current president. Katie Sargent reports.
A chaotic scene in Brasilia as police fire tear gas to break up anti-government demonstrations. Protests broke as former Brazilian president Luiz Inacio Lula da Silva was sworn in as chief of staff to the current president Dilma Rousseff. Critics say the appointment is an attempt to shield Lula from prosecution on corruption charges. Prosecutors have charged him with money laundering and fraud as part of a graft probe centred on state oil company Petrobras. As protests took place in Sao Paolo and elsewhere Thursday, a federal judge issued an injunction against Lula's appointment on the grounds it blocked "the free exercise of justice." Also on Thursday Congress began proceedings to impeach Rousseff in a separate investigation into allegations she broke budget rules to boost spending as she campaigned for re-election in 2014. Rousseff and Lula have both denied any wrongdoing in the investigations.
