 A succession of judgments by various Courts of Appeal, the Supreme Court, medical experts, etc., led to Pinochet's subsequent house arrest and release, before he died on 10 December 2006, just after having been again put under house arrest on 28 November 2006 in the Caravan of Death case.At the time of his death in 2006, Pinochet had been implicated in over 300 criminal charges for numerous human rights violations, including the Caravan of Death case (case closed in July 2002 by the Supreme Court of Chile, but re-opened in 2007 following new medical advice), Carlos Prats's assassination (case closed on 1 April 2005), Operation Condor (case closed on 17 June 2005), Operation Colombo, the Villa Grimaldi, Carmelo Soria, Calle Conferencia, Antonio Llidó and Eugenio Berrios cases, tax evasion and passport forgery.In 1998, Pinochet, who at the time continued to wield considerable influence in Chile, travelled to the United Kingdom for medical treatment; allegations have been made that he was also there to negotiate arms contracts.
