This special investigation seeks to uncover the circumstances surrounding the suicide of Ahmad Al Akabi - an asylum seeker from Iraq who was sent to an Australian detention centre and was later found hanged in November 2010. Interviews with Akabi's widow, friends and fellow asylum seekers throw light on the dangers that Akabi faced in Iraq and his experience in the Villawood Immigration & Detention facility in Sydney. But what finally tipped Ahmad Al Akabi over the edge? And who should take responsibility?
