Brazil's Lula turns himself in to police after tense showdown

The former president of Brazil, Luiz Inacio Lula da Silva, has begun a 12-year prison sentence after being convicted of corruption.

He handed himself in to police in Sao Paulo after saying farewell to supporters.

Lula, as he is popularly known, was then flown to the southern city of Curitiba where he will serve his sentence.

Some protested, believing he is innocent, while others celebrated, saying the guilty should pay for their crimes.
