Tustin used her mobile phone to record hundreds of clips of the little boy being abused, mocked and physically attacked.

In one heartbreaking audio message Arthur could be heard pleading to see his Uncle Blake, to whom he was denied access.

He could be heard saying: “Please help me, help me Uncle Blake, they’re not feeding me. I need some food and drink.”

Hughes removed his son’s favourite teddy bear and cut up his prized Birmingham City FC football shirts in front of him.

On another occasion he duped the child into thinking he was going to see his beloved grandparents – before turning around at the last minute.

In the weeks before this death they stepped up their campaign of cruelty and began poisoning him with salt. 

On June 16 last year, CCTV in Tustin’s house captured the frail, emaciated and weakened little boy struggling to pick his bedding up from the living room floor.

Hours later he was dead after collapsing with a brain injury from which he could not be saved.

Arthur was so emaciated when he eventually collapsed that medics attempting to revive him noted that they could see his ribs through his skin.

Arthur’s mother says ‘life as I know it will never exist again’ 

Madeleine Halcrow, Arthur’s grandmother, delivered a victim impact statement on behalf of her daughter, Arthur’s mother, Olivia Labinjo-Halcrow.

In the statement she said the little boy is yet to have a funeral.

The statement said: “The last time I spoke to my little boy was the most excited I had ever heard him. He knew he was going to see me soon. He asked how many packets of drumstick squashies I had saved him. I told him he could have as many packets as he wanted as long as he ate his sausage, mash and peas first.”

“He giggled his usual giggle. I will never again hear that giggle or hear him say ‘I love you mommy bear’.

“He will never get his drumstick squashies. I will never get to see the smile behind his eyes. Never get to remind him how beautiful he was and how much he was loved.

“Life as I know it will never exist again. Losing Arthur is unquantifiable. I don’t think I will ever be able to live a full life again. Grief isn’t the right word. How I feel about losing baby bear Arthur. I feel hollow. Every day I feel like I’m walking around with all the lights turned off.”
