After his arrest al-Baluchi was kept in CIA custody at undisclosed locations until 6 September 2006 when he was transferred to Guantanamo Bay Prison in Cuba. In December 2005, Human Rights Watch listed him as a "ghost detainee" held in the CIA prison system. During al-Baluchi's secret detention, he was tortured by the CIA using many so-called "enhanced interrogation techniques". Officials reported: "al-Baluchi was tortured and forcibly dunked into a tub filled with ice water. CIA interrogators forcibly kept his head under water while he struggled to breathe and beat him repeatedly with a truncheon-like object hitting him and smashing his head against a wall."
