Program: Thin Black Line

Depending on who you ask, the infamous 1993 death in custody of Aboriginal teenager Daniel Yock is either a tragic incident or unfinished business.

On a spring afternoon in Brisbane's Musgrave Park, the 18-year-old traditional dancer and amateur boxer is drinking with his mates.

But when a police van arrives, the mood suddenly changes, triggering a dramatic chain of events.

Presented by Walkley Award-winning investigative journalist Allan Clarke, Thin Black Line is a deep dive into what happened that day — according to the one eyewitness who saw it all unfold, speaking publicly for the first time in almost three decades.

His still-grieving family believe that not only could Daniel's death have been prevented, but that he shouldn't have been arrested in the first place.
