CAIRO, May 30 (Aswat Masriya) - Egyptian authorities released early Saturday imprisoned dual national Mohamed Soltan, after he revoked his Egyptian citizenship, his lawyer said.

Soltan, who is the son of Brotherhood leading figure Salah Soltan, was sentenced to life in prison on April 11 for managing an "operations room" following the dispersal of the two pro-Mohamed Mursi camps in August 2013.

His father meanwhile was sentenced to death, alongside Muslim Brotherhood Supreme Guide Mohamed Badie and 12 others.

Halim Hanish, one of Soltan's lawyer, said his release was per a presidential decree issued last November that allows deportation of foreign defendants and convicts "whenever the [state's] supreme interest necessitates so." 

Mohamed originally held a United States citizenship alongside his Egyptian citizenship. He was released at 7 a.m. this morning and is currently on a plane to the U.S., Hanish said.

"After extensive efforts, the U.S. Government has successfully secured Mohamed’s deportation back home to the U.S., mercifully concluding this dark chapter for Mohamed and our family," Soltan's family said in a statement published on Facebook.

Egypt's top prosecutor told the state news agency MENA that Soltan was deported to serve the remainder of his prison sentence, 25 years, in the U.S.

Soltan has been on hunger strike since January 2014 in protest over his detention, maintaining the longest hunger strike among those detained in Egypt. Soltan has repeatedly refused to end his strike and his life is believed to be in danger.

Soltan's family described his health as "dire", adding that "he will receive medical treatment as soon as he arrives on U.S soil and will spend the immediate future with his family recovering."

Soltan was arrested from his home on August 27, 2013 after the deadly dispersal of two camps set up in support of former President Mohamed Mursi following his ouster in July 2013.

Another jailed detainee who benefited from the November decree is Australian national Peter Greste, who was arrested in December 2013 and charged, alongside two other Al-Jazeera network journalists, with "spreading false news."

They had initially been sentenced to prison in June 2014 but a court ordered their retrial in January. 

Greste was released from prison on February 1 after spending 400 days in prison. He was immediately deported to Australia, yet he remains facing trial in absentia and risks being found guilty if he fails to attend the court hearings, he told Reuters on Friday.
