(CNN) -- An American arrested after a car bombing in northern Sinai in August was found dead in an Egyptian police station Sunday, authorities said. 
 
 The man -- identified as James Lunn by a U.S. State Department official -- was discovered hanging by his shoelaces and a belt from a bathroom door in a waiting area of the Awal police station in Ismailia, Egypt, public prosecutor Hisham Barakt said. 
 
 An investigation has been ordered to determine if the death was a suicide, Barakt said. 
 
 Lunn was taken into custody on August 27 after a car bomb exploded near a police station in northern Sinai, according to a statement from Egypt's Interior Ministry. His death came on the same day that his detention was extended for another 30 days, the ministry said. 
 
 Investigators found "a computer and maps of vital installations" in his possession after he was detained, the ministry said 
 
 "The duty officer in the Awal Police Station in Ismailia, while passing by the administrative detention room where the accused was being held alone, found that the accused had committed suicide by hanging himself from the bathroom door," the ministry statement said. 
 
 A vice consul from the U.S. government visited the man at the jail "and noted the good treatment of the prisoner," the ministry said. 
 
 "Our thoughts are with his family as they cope with their loss," the State Department official said. "We have contacted his family and are providing appropriate consular assistance." 
 
 Personnel at the U.S. Embassy in Cairo were "in regular touch with Mr. Lunn during his detention," the official said.

 (AFP) – 2 days ago 
 
 Cairo — An American man detained for more than a month was found hanged in his prison cell in the Egyptian city of Ismailiya on Sunday after committing suicide, security officials said. 
 
 A US State Department official confirmed the death of James Lunn and expressed its condolences to his family. 
 
 The Egyptian security officials said the body of Lunn, whom they had identified as James Henry, 55, was found at noon at Ismailiya Awal police station of the Suez Canal city. 
 
 A prosecutor had decided on Saturday to extend his detention for 30 days, the interior ministry said in a statement. 
 
 A report from the prosecutor's office, forwarded to journalists by the foreign ministry, said Lunn had hanged himself with a shoelace and a belt. 
 
 The interior ministry said Lunn was arrested on August 27 in Sheikh Zuwayid in a security sweep after a car bomb targeted the police station in the North Sinai town. 
 
 He was found in possession of a "computer and maps of important installations." 
 
 Security officials said he was detained for violating a curfew imposed because of the wave of political unrest sweeping the country. 
 
 Lunn was stopped on the road between El-Arish and Rafah in North Sinai and told authorities he was on his way to the neighbouring Gaza Strip. 
 
 The State Department official said they had been "in regular touch" with Lunn since August 28, a day after his arrest, speaking to him over the phone. 
 
 A consular officer had been allowed to visit him on October 8, the official said. 
 
 "At no time did Mr Lunn claim to our consular personnel that he had been subjected to any form of maltreatment," the official added. 
 
 Lunn was the second foreigner known to have died in an Egyptian jail since a popular military coup overthrew president Mohamed Morsi in July, leading to a state of emergency and a curfew to deal with an Islamist backlash. 
 
 In September, a French citizen was beaten to death by cellmates in a Cairo prison. He had apparently been arrested at a checkpoint.

– A US citizen arrested in Egypt in relation to a car bombing has been found dead in his cell at an Egyptian police station, after apparently hanging himself with his shoelace and belt, according to local officials. James Lunn, 55, was taken in by Egyptian police over a month ago after he was found in possession of a "computer and maps of important installations" following a car bomb explosion in a North Sinai town. The day he died, a prosecutor had just extended his detention for another 30 days, AFP reports. "The duty officer in the Awal Police Station in Ismailia, while passing by the administrative detention room where the accused was being held alone, found that the accused had committed suicide by hanging himself from the bathroom door," Egypt's Interior Ministry says in a statement, per CNN. The US State Department says it had been "in regular touch" with Lunn since his arrest, and a consular official visited him last week. "At no time did Mr Lunn claim to our consular personnel that he had been subjected to any form of maltreatment," says a department spokesperson, per AFP.
