Police Commissioner Karl O’Callaghan has apologised to Aboriginal man Gene Gibson, who was wrongly jailed for the manslaughter of Josh Warneke in 2010.

Mr Gibson was released from prison, after the Court of Appeal threw out his manslaughter conviction, finding he did not have the cognitive ability or language skills to understand what was happening during the legal process.

Mr O’Callaghan told The Morning Show’s Gareth Parker, the police interview process had been a shambles.
