TWO prisoners have been jailed for a total of 26 years following a violent assault on a fellow inmate.

Anthony Mark Rickett, 29, formerly of Mexborough, and Joel Jan Fletcher, 23, slashed another man across the face in January 2016, leaving him with serious injuries and permanent scarring.

They had planned the attack and covered the CCTV cameras. The weapons used were never recovered.

Fletcher was due to go on trial at Sheffield Crown Court in January this year charged with grievous bodily harm with intent. He pleaded guilty at the start of the trial and was jailed on Monday for 13-years and six months, with an additional three years on licence at the end of his sentence.

Rickett, who was found guilty of grievous bodily harm with intent following a trial in January this year, was sentenced to 12-years and six months in prison.

Rickett was serving a sentence for robbery at the time of the assault, but was released last year to his address in Mexborough. He was remanded back to prison after being found guilty of the attack.

The court was told that on Friday January 22, 2016, Fletcher and Rickett attacked a 49-year-old man who was also an inmate at HMP Doncaster.

They entered his cell, locking the door behind them and slashed the 49-year-old across the face.

Temporary Detective Sergeant Alex Dorlin, from the Prison Investigation Team, said: “This was a nasty and vicious attack against a man in his cell, which has resulted in him being scarred for life.

“The assault was planned with the CCTV cameras being covered and the weapons used never being recovered.

“Fletcher and Rickett’s actions that morning were appalling and I am pleased they received lengthy custodial sentences for their violent crime.”
