THE family of Sheku Bayoh have slammed a former lord advocate for failing to challenge unconscious bias in the investigation into his death.

Mr Bayoh died of positional asphyxiation on May 3 2015 after being bound hand and foot, with six police officers on top of him.

Allegations of racism have long dogged the case, from the initial phone call that sparked the police response to the handling of the investigation into Bayoh’s death, prompting then chief constable of Police Scotland Iain Livingstone to admit last year that his force was “institutionally racist.”
