Brazilian police have arrested fugitive Italian writer Cesare Battisti, a former communist militant convicted of murder in his home country. Cesare Battisti was charged with murdering four people in Italy between 1978 and 1979. He escaped from jail, in Italy in 1981, while awaiting trial. He was convicted in absentia in 1990. He went on to become a successful writer of police novels in France and Mexico, before escaping to Brazil in 2004. Battisti was arrested in Brazil in 2007, prompting the Italian goverment to request his extradition under an existing bilateral treaty. He was granted asylum in Brazil four years ago, but earlier this month a judge ruled that he should be deported to serve his sentence. If deported, Battisti, 60, would be sent to either France or Mexico, which could then extradite him to Italy. He will remain in jail until there is a final decision on his deportation. The process is expected to take months.
