Ollanta Humala, Peru's former left-leaning president who was ordered to spend 18 months in pre-trial detention, on Friday was moved to a prison built for his longtime foe, the ex-autocratic leader Alberto Fujimori.

Fujimori, 78, has spent the past decade as the lone inmate in Barbadillo prison, nestled in a police base on the outskirts of Lima, where he is serving a 25-year sentence for human rights crimes during his 1990-2000 right-wing government.

Humala, a former military officer whose five-year term ended a year ago, was transferred via police helicopter to Barbadillo where he will be held in custody until prosecutors conclude their money laundering investigation. Humala's attorneys had sought better conditions for their client than Peru's overcrowded jails.
