Lima, Peru (CNN) -- Family members requested a humanitarian pardon Wednesday for former Peruvian strongman Alberto Fujimori, saying he should be released from prison because of health problems. The 74-year-old Fujimori is serving four concurrent sentences, the longest of which is 25 years, for corruption and human rights abuses. He underwent surgery September 19 for a recurring lesion in his tongue and returned to the clinic nine days later because of problems with scarring of the wound, the state-run Andina news agency reported. 2011: Longtime Peruvian fugitive turns himself in "This request is argued on the basis of medical facts," said Keiko Fujimori, the former president's daughter, who was quoted by Andina.
