The centrist government of President Pedro Pablo Kuczynski said Friday that it has rejected a new request to free imprisoned former authoritarian leader Alberto Fujimori filed by a supporter because it did not meet basic requirements.

Justice Minister Marisol Perez Tello said the paperwork reached the government early this month but was declared inadmissible days ago because it lacked the signature of Fujimori or one of his relatives.

"It is another process that unfortunately ends . . . because of reasons of form and without a decision on the core issue," Perez told reporters in comments broadcast on TV station Canal N.
