Arthur Labinjo-Hughes' killer dad has been moved to another prison, although Government officials have denied he was attacked.
Arthur, six, died in 2020 after being starved, tortured and poisoned with salt by his dad Thomas Hughes, 29, and stepmum Emma Tustin, 32.
Tustin was jailed for life with a minimum term of 29 years for murdering Arthur, while Hughes was sentenced to 21 years in prison for manslaughter.
