An inmate at Wakefield prison is held in one of the UK’s most secure cells - a glass box buried underneath the prison - and is thought to be so dangerous he will never be released.
Robert Maudsley is known as the ‘brain eater’ by his fellow inmates and is let out of his cell for just one hour a day, guarded by six people at all times.
He was in his early 20s when he committed his first murder and was jailed - but this didn’t stop him and he continued to kill once inside.
