The intelligence arm of the
Islamic Revolutionary Guard Corps arrested Moore-Gilbert in September 2018 at
Tehran Airport as she was leaving the country after attending an academic conference. She was subsequently tried and sentenced to ten years in prison for
espionage. Moore-Gilbert was held in
Evin Prison in
solitary confinement. In a phone call with
Reza Khandan, the husband of jailed human rights lawyer
Nasrin Sotoudeh, Moore-Gilbert said she felt hopeless, isolated, and unable to eat. Speaking
Persian on the call, she said "I am so depressed. I don't have any phone card to call. I've asked the prison officers but they didn't give me a phone card. I [was last able to] call my parents about one month ago." After she was jailed, Moore-Gilbert launched a campaign of resistance, including staging several
hunger strikes and even escaping from the prison yard onto the roof of the IRGC interrogation block. In May 2020, her family denied reports that she had attempted suicide in prison, or that she had been tortured by the Islamic Revolutionary Guards.
The Sunday Times reported in June 2020 that sources close to Moore-Gilbert's family had informed it of her receiving beatings at the hands of guards, due to her looking out for new prisoners, and suffered injuries on her hands and arms. They also said that the governor of Evin Prison had ordered her to be drugged to break her resistance. One source said that the beatings had caused her to repeatedly fall unconscious and she had major bruises over her entire body. Richard Ratcliffe, husband of
Nazanin Zaghari-Ratcliffe who was also held in Evin prison, said Moore-Gilbert was being kept in solitary confinement and was being severely abused, which shocked Iranian activists who knew about it. In August 2020, the Australian
60 Minutes program on the
Nine Network aired an episode called "Living Hell" about her imprisonment. On 24 October 2020, Moore-Gilbert was said to have been transferred from Gharchak to an unknown location. Australian Foreign Minister
Marise Payne said the Australian Government was "seeking further information" about Moore-Gilbert's location. On 29 October 2020, Moore-Gilbert was returned to Evin Prison. On 25 November 2020, Iranian state media announced that Moore-Gilbert had been released as part of a
prisoner exchange. The Young Journalists Club, a
news agency affiliated with Iranian state media, stated that Moore-Gilbert was a "dual national spy [...] who worked for the Zionist regime", and that she had been exchanged for an Iranian 'businessman' and two other Iranian citizens who had been held overseas. During her detainment, the official advice to her family from the Australian Government was to keep a low profile, however in 2022 Moore-Gilbert said that greater media attention on her detention would have helped apply more pressure on both the Iranian government and the Department of Foreign Affairs and Trade to negotiate her release. == After release from prison ==
