Former Brazilian President Luiz Inacio Lula da Silva turned himself in to police on Saturday, ending a day-long standoff to begin serving a 12-year prison sentence for corruption that derails his bid to return to power.
Lula was flown by police to the southern city of Curitiba, where he was tried and convicted late last year, and taken to the federal police headquarters there to serve his sentence. Protesters supporting Lula clashed with police outside the walls of the building. Officers used stun grenades, tear gas and rubber bullets to disperse the crowd.
