Lahcen Ikassrien

On June 16, 2014, he was arrested in Madrid accused of jihadism. He received a 10 year sentence, on September 30, 2016, after being convicted of recruiting individuals to go to war-torn Syria. Ikassrien alleged that he and other Guantanamo Bay detainees were tortured during their detention, and a Spanish magisterial investigation concluded that they had been subject to abusive interrogation techniques.

Subsequently, the Department of Defense instituted the Combatant Status Review Tribunals. The Tribunals, however, were not authorized to determine whether the captives were lawful combatants—rather they were merely empowered to make a recommendation as to whether the captive had previously been correctly determined to match the Bush administration's definition of an enemy combatant.

On April 29, 2009, that Spanish investigating magistrate Baltasar Garzon initiated a formal investigation into whether confessions from Ikassrien, and three other former Guantanamo captives were the result of the use of abusive interrogation techniques. Ikassrien, and the other three men: Hamed Abderrahman Ahmed, Jamiel Abdul Latif al Banna and Omar Deghayes, had previously faced charges in Spanish courts, based on confessions they made while in US custody. Their charges had been dropped based on their claims that their confessions were false and were the result of abusive interrogation techniques.

The International Herald Tribune reported that Ikassrien was acquitted on October 11, 2006.

On November 19, 2006, El País published an article in which Ikassrien alleges that he had been tortured repeatedly over the course of a month during his detention in Kandahar. He alleges that he was subjected to various forms of torture, including being trapped with aggressive dogs, being tied up, and that soldiers held him in a cage where they showered him with feces and urine while calling him "Animal No. 64".

On July 3, 2005, Ikassrien was extradited to stand trial in Spain.

Originally the Bush Presidency asserted that captives apprehended in the "war on terror" were not covered by the Geneva Conventions, and could be held indefinitely, without charge, and without an open and transparent review of the justifications for their detention. In 2004 the United States Supreme Court ruled, in Rasul v. Bush, that Guantanamo captives were entitled to being informed of the allegations justifying their detention, and were entitled to try to refute them.

Lahcen Ikassrien is a citizen of Morocco who was held in extrajudicial detention in the United States Guantanamo Bay detainment camps, in Cuba. Ikassrien's Guantanamo ISN was 72. The Department of Defense reports that Ikassrien was born on October 2, 1972, in Targist, Morocco.
