Negligence by the Israeli Prison service played a role in the suicide of Ben Zygier, the reputed Mossad agent outed as Israel's "Prisoner X," an internal report released Thursday said.
Zygier was found hanged in his cell on December 15, 2010, after tying a bed sheet to the bars of his prison bathroom window and using the other end as a noose. He had been held incommunicado for 10 months, dpa reported.
The investigation conducted into his death concluded that there exists "prima facie evidence" that failures by specific Israel Prison service employees were responsible for the suicide.
Zygier should have been kept under constant supervision, District Court Judge Daphna Blatman-Kedrai wrote in her report.
Israel has not yet indicated why Zygier, a Melbourne native, was jailed. Australia has demanded more information on the case.
