Sunday Dare, 59, today said his grandson Isa Dare, is too young to know what he was doing after video emerged yesterday of him pressing the button which appears to detonate explosives in a car containing four alleged spies.
Today, a neighbor claimed he had been evicted from his home in Deptford, south east London, after removal vans were seen carrying away his belongings.
But removal workers from Roberts and Dennys were unaware of his situation and said they were taking his belongings - including a stereo, mattress and a portrait of Jesus - to storage.
Young Isa Dare, the son of Grace 'Khadija' Dare from south east London, pushes the button that blows up four alleged spies sitting in a white car behind him.
Standing triumphantly next to the charred remains of the car, his hand raised to the sky, the boy then yells: 'Allahu Akbar.'
It is the second time the young boy, who was brainwashed after his mother took him to Syria three years ago, has appeared in one of the terrorists' propaganda videos.
His grandfather told of how the child begged him to save him just days before he was forced to appear in the first video last month.
In what was seen as a 'promotion' of this latest murderous release, Dare was made to declare: 'We are going to kill the kuffar [non-believers] over there' - before pointing to the men killed in today's video.
The latest video, which is believed to be shot in ISIS's de facto capital of Raqqa, was entitled: 'they are the enemy so be aware of them.'
One by one, each man confessed to either spying on, or conspiring against, ISIS. They were later seen handcuffed to the inside of a car - with a look of utter fear in their eyes.
Before they were killed, the senior ISIS commander standing next to the boy threatened British Prime Minister David Cameron for arming the terror group's enemies in Syria.
Young Dare was brainwashed by ISIS fanatics after his mother, 24, who had links to Lee Rigby's killer, brought him to the warzone.
However, his grandfather, known as Henry, said Isa made a desperate plea for help during a heartbreaking phone call just days before he featured in the barbaric stunt, saying: 'Please save me.'
It later emerged that Isa's father had made a desperate attempt to rescue his son after his estranged wife fled to Syria and married an ISIS militant.
Asked if he thought his grandson had any idea what he was saying in the video, Mr. Dare – of Deptford, south east London – said: 'No – he's a kid.
'He's a minor, he's under five. He's acting under the influence of ISIS guerrillas. He's too young. He's propaganda. They are just using a small boy. They are using him as a shield.'
Mr. Dare said he had reported Grace to the police on three occasions before she left for Syria and told them 'she's behaving in a very funny way'.
However, the grandfather is believed to have been evicted from his home on the day that he publicly condemned the killings, explaining that his four-year-old grandson was too young to know what he was doing.
Asked again today what he thought if the video, he said: 'I saw it in the newspaper. I can't speak at the moment I am driving.'
He previously lived in a council flat in Deptford, south east London, but today a removal service was moving his belongings at the request of Lewisham Homes.
One neighbour said: 'I heard he's been evicted,' Daily Mail reported.
