Ben Zygier was an Australian-Israeli citizen who was a veteran of the Israel Defense Forces and allegedly an agent of Mossad. He was imprisoned in Ayalon Prison, Ramla, Israel and died in custody in 2010, reportedly by hanging himself in a maximum-security cell designed to be suicide-proof.

His findings were reported in February 2013 on the ABC television program Foreign Correspondent, which claimed there was strong evidence that Prisoner X was Ben Zygier, a dual citizen of Israel and Australia, and who carried an Australian passport in the name of Ben Allen.
