A RACIST killer has been handed extra time in jail for an attack of a fellow inmate who was left brain damaged.

Christopher Miller kicked and repeatedly stamped on Joseph Wedlock in an assault caught on CCTV at HMP Addiewell on September 7 2021.

Wedlock ended up in rehab for almost a year and now stays with his mother with him no longer able to live on his own.

Miller was yesterday sentenced to four years and eight months at the High Court in Glasgow for the attack.

He returned there having been jailed for a minimum 18 years in 2009 for the racially motivated murder of Merchant Nay officer Kunal Mohanty in the city's Gorbals.

In a crime which shocked the country at the time, jurors heard how he slit the throat of the 30 year-old, who had travelled from India to build a better life for his family.

As the victim lay dying, Miller boasted to a friend: "I've just done a P**i."

The latest jail-term will run consecutive to the life sentence.

The court heard how the attack at HMP Addiewell came amid unrest in the prison at the time.

Prosecutor Angela Gray said this centred around "bullying allegations".

CCTV captured Wedlock initially being shoved to the ground by another inmate.

He walked off before more fighting broke out between prisoners. Wedlock again ended up on the floor.

Miss Gray: "He tried to get back to his feet, but Christopher Miller kicked him on the head and, while lying motionless, he then repeatedly stamped on him."

Staff stepped in before a badly hurt Wedlock was rushed to hospital.

Medics found he had suffered a "traumatic" brain injury and fractures.

He was initially kept in hospital for five weeks before being transferred to a rehab centre, which he only left in August this year.

The court heard Wedlock remains affected by what happened including needing help with simple chores.

Miller's KC John Scullion said the killer struck having been among a number of inmates who had taken street Valium that day.

Miller pleaded guilty to assaulting Wedlock to his severe injury, permanent disfigurement and impairment as well as to the danger of his life.

Lord Richardson cut the sentence from seven years due to his guilty plea.

The judge said: "Your attack was horrendous. I have seen the CCTV - you kicked him and stamped on him, I counted, at least 10 times while he was unconscious and on the floor."
