Styles Isaac King, an Aboriginal man aged 30, died from traumatic asphyxiation following restraint by crowd controllers at a bar in Katherine, Northern Territory. During an altercation, he was held face-down on the floor in a headlock by Mr Hoermann (197cm, 110.5kg) with Mr Clark applying additional weight via his knees for over 7 minutes. The deceased called out he could not breathe, but restraint continued. King was unresponsive when released, and despite resuscitation attempts, was pronounced dead at hospital. The coroner found inadequate training on positional asphyxia risks among crowd controllers—only 'threadbare' references existed in training materials, with no formal assessment. Both men lacked knowledge of positional asphyxia risks, headlock dangers, and the lethal consequences of prolonged prone restraint. The coroner emphasized improved training and clear safety guidelines were essential to prevent similar deaths, particularly given contributing factors of obesity, alcohol intoxication, and use of prohibited restraint techniques.

Coroner's recommendations
Improve and clarify training on positional asphyxia risks in crowd controller certification courses—curriculum currently inadequate and should be more directed and assessed
Licensing authority should work with registered training organisations and industry to explicitly embed knowledge and skill requirements addressing positional asphyxia in security operations units of competency
Implement mandatory refresher training for current crowd controller licensees on safe restraint techniques, communication, negotiation, and application of force prior to licence renewal
Katherine Hotel to include specific language in its Code of Conduct warning against holding persons face-down by force and clearly stating the risk of death; align with Director-General of Licensing Practice Direction on asphyxia risks
Minister for Business to conduct review of NT competency standards and training requirements for crowd controllers, considering introduction of refresher training in cross-cultural communication, negotiation, and safe application of force
Align NT security licensing requirements with national standards being developed following ASQA review recommendations, ensuring single set of competency standards across jurisdictions
