Mohamedou Ould Slahi () (born December 21, 1970) is a Mauritanian citizen who was detained at Guantánamo Bay detention camp without charge from 2002 until his release on October 17, 2016. Slahi traveled from his home in Germany to Afghanistan in December 1990 "to support the mujahideen." Slahi trained in an al Qaeda camp and swore allegiance to the organization in March 1991. He returned to Germany soon after, but traveled back to Afghanistan for two months in early 1992. Slahi said that, after leaving Afghanistan the second time, he "severed all ties with ... al-Qaeda." The U.S. government maintains that Slahi "recruited for al-Qaeda and provided it with other support" since then. He lived in Montreal, Quebec, Canada from November 1999 to January 2000. Slahi was suspected of involvement in the attempted LAX bombing and was investigated by the Canadian Security Intelligence Service. Due to the scrutiny, Slahi returned to live in Mauritania where he was questioned and cleared of involvement. After the September 11 attacks, the U.S. again was interested in Slahi. He was brought in for questioning by Mauritanian authorities on November 20, 2001, after which he was detained for seven days and questioned by Mauritanian officers and by agents of the U.S. Federal Bureau of Investigation (FBI). The CIA then transported Slahi to a Jordanian prison through its extraordinary rendition program; he was held for eight months. Slahi said he was tortured by the Jordanians. After being flown to Afghanistan and held for two weeks, he was transferred to military custody and the Guantánamo Bay detention camp in Cuba on August 4, 2002, under the authority of the 2001 Authorization for Use of Military Force (AUMF). Slahi was subjected to sleep deprivation, isolation, temperature extremes, beatings and sexual humiliation at Guantánamo. In one documented incident, he was blindfolded and taken out to sea in a boat for a mock execution. Lt. Col Stuart Couch refused to prosecute Slahi in a Military Commission in 2003. He said that "Salahi's incriminating statements—the core of the government's case—had been taken through torture, rendering them inadmissible under U.S. and international law." In 2005, the internationally recognized criminal defense lawyer Nancy Hollander got involved in Slahi’s case, together with lawyer Theresa Duncan. They argued Slahi’s rights to a fair trial, despite criticism for defending a terrorist suspect. In 2010, Judge James Robertson granted a writ of habeas corpus, ordering Slahi to
