SANTIAGO, Chile (AP) -- Former Peruvian President Alberto Fujimori on Tuesday lost a second bid to be released from his eight-day arrest as he fights extradition to Peru on human rights and corruption charges.A three-member panel of the Santiago Court of Appeals turned down a request for Fujimori's release, ruling that the arrest of the 67-year-old former president was legal, according to one of the judges, Lamberto Cisternas.That means Fujimori, who is being held at an academy for corrections officers, will remain under arrest as Peru pursues his extradition on 21 charges of corruption and human rights stemming from his 1990-2000 government.The request on behalf of Fujimori was filed by Antonio Marin, a private citizen whose connection to Fujimori was unclear.It was the second time Fujimori was rejected for release while awaiting an extradition trial. Supreme Court justice Orlando Alvarez rejected another such petition on November 7, just hours after ordering Fujimori's arrest as the former Peruvian leader returned from five years of protected exile in Japan.Fujimori fled to Japan in 2000 as his government collapsed amid a corruption scandal. He resigned the presidency in a fax sent from Tokyo.He said he came to Chile only as a stopover on his way back to Peru to again seek the presidency in elections set for April 2006, in spite of a congressional ban on Fujimori holding any public office until 2011.Relatives and aides who have visited him in Chile have also said he aims to mount a new presidential candidacy, prompting the Chilean government to warn them that they must abstain from campaign or political activities in Chile. Foes and supporters of Fujimori have staged peaceful demonstrations in front of the academy where he is being held.The Chilean lawyer hired by the Peruvian government, Alfredo Etcheberry, said a formal extradition request will be filed close to the 60-day deadline that expires in mid-January. In all, the trial should take about four months, legal experts say.At home, Fujimori faces charges ranging from abuse of power and corruption to sanctioning a paramilitary death squad. The death squad allegedly committed two massacres of suspected guerrilla collaborators in which 25 people were killed, including an 8-year-old boy.Peruvian prosecutors are seeking a 30-year sentence and a $29 million fine for his alleged role in the death squad killings, the most serious charge he faces.Copyright 2005 The Associated Press.
