DS Hunt had been called to an assault in a pub in Larkhall – a teenager, suspected of slashing a man in the back, had fled the scene.
The detective identified the suspect and decided to go to his home to arrest him.
Mr Hunt, 60, told the BBC’s Radio Scotland Breakfast programme how a “whole host” of family members came out of the property armed with poles, knives and sticks and attacked DS Hunt and his three detective constables.
“My father corralled his men back shouting ‘Get back to the car’ and at that point he was overcome by one of the individuals who sat astride him and began stabbing him, kicking him, punching him – one kick even lifted his body into the air according to witnesses.
“It was just a frenzied attack.”
By the time officers were able to get back-up on the scene, DS Hunt was lying badly injured in the street. He was taken to hospital, but his son believes he was dead on arrival.
DS Hunt, aged 56, was nine months away from retirement.
Following a trial at the Glasgow High Court, three members of the family – two men and a woman – were convicted of his murder.
