April 29 (UPI) -- One of two accused spies who were arrested by Turkish authorities this month committed suicide in prison, authorities said Monday.
Prosecutors said an investigation is determining the formal cause of death. Authorities detained Hasan and another suspect on April 15 and say both confessed to being intelligence operatives for the United Arab Emirates.
Authorities arrested the men in connection with a probe targeting spying by the UAE. Prosecutors charged the men with political, military and international espionage.
One suspect arrived shortly after Washington Post journalist Jamal Khashoggi went missing at the Saudi Arabia consulate in Istanbul, as part of a purported spy ring intended to create an "anti-Turkey structure."
Hasan arrived in Turkey five months later to help spy, prosecutors said. Istanbul police said they started a joint investigation to follow the men once they learned they were working together.
