Israeli investigation says mysterious 'Prisoner X" hung himself in prison cell

Israel has partially lifted a gag order over the investigation into the death of an Australian-Israeli man in an Israeli prison two years ago. The probe rules that the man known as "Prisoner X" hung himself.

The story has dominated headlines in Israel for the past week. According to Australian media, the man, identified as Ben Zygier, worked for Israel's Mossad spy agency and was mysteriously imprisoned by Israel in 2010 for unspecified security offenses.

Israel kept the case under wraps for more than two years, acknowledging it last week only 24 hours after Australian ABC broke the story.

According to the new information released Tuesday, Israel concluded the prisoner killed himself on Dec. 15, 2010, by hanging himself with a bed sheet from the bathroom window in his cell.
