Overview
- A Supreme preparatory court resolution issued on October 16 keeps Castillo’s preventive detention in force until March 8, 2027, and he remains held at the Barbadillo prison.
- Judge Juan Carlos Checkley declared the review of the measure "infundada" and preserved a 12‑month extension first ordered on February 27, 2026 and confirmed by the Sala Penal Permanente on June 1.
- The Public Prosecutor’s Office told the court that newly incorporated testimony, forensic reports and seized documents strengthen its allegation that Castillo led an organized criminal structure tied to state agencies.
- The fiscal inquiry covers three main lines: alleged intervention in Petroperú appointments and a biodiesel purchase, irregular contracting including the Puente Tarata III at Provías Descentralizado, and alleged directioning of sanitation and public works at the Ministry of Housing.
- Castillo also faces a separate first‑instance sentence from December 4, 2025 for conspiracy to rebellion, and continued detention limits his ability to participate in the investigation while prosecutors add expert and testimonial evidence that could lead to formal charges.
