A pensioner had a red-hot iron strapped to his back by robbers desperate to find out where he kept his valuables.
David Ward was tortured for 30 minutes by the raiders who also boiled a kettle and threatened to pour scalding water on his three-year-old granddaughter in an attack so sickening that police say it has even outraged the criminal fraternity.
Terrified Ann Woodland, 66, was handcuffed to her partner throughout the ordeal, during which the robbers stole £200,000 worth of jewellery.
'I became hysterical when they said they were going to boil the kettle so they could pour it over my granddaughter. What kind of animals threatens to do that to a child?'
Mr Ward added: 'I could feel the iron searing into me but I didn't say anything, I didn't want to wake up Ann's granddaughter.
'I will never, ever forget how that felt. Now I just feel angry, how can they treat someone like that, how can they just ruin your life like that?'
Eventually the robbers left, leaving the couple handcuffed to a radiator in a darkened bedroom with only the three-year-old to help rescue them.
Miss Woodland said: 'We called her into the bedroom and tried to make it a joke and fun so she didn't get scared. I said we had been silly and got tied up and she managed to get the key for us from the dressing table. Thank God she didn't wake up while they were there.'
'Mr Ward's injury was a full thickness burn, it burned through the layers of his skin, through the fat and into the muscle.'
