He was arrested by the Federal Bureau of Investigation (FBI) on Tuesday November 5th at the US Embassy in Phnom Penh in Cambodia where he was stationed and was sent to appear in the nearest federal court in Guam on Thursday the 7th to be charged. After his initial court appearance and indictment, Rahman, was transferred to a federal prison in Virginia.

Rahman was a CIA analyst with a top-secret clearance that gave him access to the classified material that passed through the Agency's Cambodia Station, which would have included much of the routine collection and dissemination of information on developments in Asia. Rahman allegedly selected one report containing two files relating to plans by Israel to attack Iran, which he then placed on an Iranian frequented site on the Telegram messaging app called the "Middle East Spectator," which in turn claimed that the information came from a Pentagon source. After being posted it attracted a considerable audience, including US security monitors, numerous Iranians and, inevitably, the Israelis. The two top secret documents were marked as having been produced by the US government's National Geospatial-Intelligence Agency and the National Security Agency. They included satellite imagery from October 15th and 16th that showed that Israel was moving Air Force military assets preparatory to conducting a military strike on Iran. Bear in mind that Israel has long sought to eliminate Iran as an adversary in the Middle East region they share, up to and including assassination of Iranian scientists and government officials and air attacks on targets in places like Syria that have been regarded as Iranian allies. Iran, for its part, has never attacked Israel prior to recent developments relating to the Gaza conflict.

The US government declared the leak of the classified files to be "deeply disturbing" and investigators who finally focused on Rahman declared that he might have been "ideologically" motivated to expose the information. Rahman has declared himself to be not guilty and as the case relates to intelligence on a non-allied foreign country's military making preparations for war it raises some ethical problems as well as political issues connected to Israel's unofficial special relationship with the United States government. It is, for example, not normal for someone detained for leaking classified information to be imprisoned as the preparations for trial are underway unless they are likely to flee jurisdiction. Rahman is from a prominent and wealthy family based in Vienna Virginia and his father Muhit Rahman and lawyer Amy Jeffress sought to have him stay at home with family in custodial pretrial, which is normal, but a ruling by US District Judge Patricia Tolliver Giles overruled a magistrate who said a week before that Rahman could be free of additional restrictions including detention while he is awaited his trial. Jeffress has indicated that she will be appealing the detention order which was restored by Giles.
