Indonesian authorities also believe more suspects remain at large. In 2005, Indonesian police arrested 24 additional people suspected of involvement in the Bali attacks and a 2003 bombing of the Marriott Hotel in Jakarta. On 12 October 2005, a story in Australian broadcaster SBS's documentary series "Dateline", called "Inside Indonesia's War on Terrorism", argued that the Indonesian military or police may have been involved in executing the attack. On 13 June 2007, it was reported that Abu Dujana, who might have headed a terrorist cell in Bali, was captured. Just past midnight on 9 November 2008, the three convicted of carrying out the bombings (Imam Samudra, Amrozi Nurhasyim, and Ali Ghufron) were executed by a firing squad. Umar Patek was finally arrested in Abbottabad Pakistan in early 2011. The U.S. government had offered a US$1 million reward for his arrest. Patek is a suspect in other bombings as well as the one in Bali. In April 2003, Indonesian authorities charged Abu Bakar Bashir (also rendered "Ba'asyir"), the alleged spiritual leader of Jemaah Islamiyah, with treason. It was alleged that he tried to overthrow the government and establish an Islamic state. The specific charges against Bashir related to a series of church bombings on Christmas Eve in 2000, and to a plot to bomb United States and other Western interests in Singapore. He was initially not charged over the Bali attack, although he was frequently accused of being the instigator or inspirer of the attack. On 2 September, Bashir was acquitted of treason but convicted of lesser charges and sentenced to a prison term of four years. He said he would appeal. On 15 October 2004, he was arrested by the Indonesian authorities and charged with involvement in another bomb attack, which killed 14 people at the J. W. Marriott hotel in Jakarta on 5 August 2003. Secondary charges in this indictment accused him of involvement in the Bali bombing, the first time he faced charges in relation to this attack. On 3 March 2005, Bashir was found not guilty of the charges surrounding the 2003 bombing, but guilty of conspiracy over the 2002 attacks in Bali. He was sentenced to two and a half years imprisonment. The Australian, US, and many governments expressed its disappointment that the sentence was too short; in the outcome, Bashir was freed 14 June 2006 having served less than 26 months for his conspiracy, and on 21 December 2006, Bashir's conviction was overturned by Indonesia's Supreme Court.
