A HMP Risley prisoner who attacked a fellow inmate with razor blades has had two years added to his jail term.

Convicted robber Jamie Johnson attempted to slash a love rival in the prison's healthcare clinic with an improvised weapon.

And on Wednesday, April 10, the 29-year-old was ordered to serve additional time behind bars by a judge.

Liverpool Crown Court heard that Johnson and fellow prisoner Declan Dolan were in a holding area in the clinic of the category C Warrington Road prison at around 8.30am on Wednesday, November 7.

The defendant then lunged at his victim, the boyfriend of his ex-partner, with a marker pen which had had the nib removed and replaced with two razor blades.

Johnson then followed his love rival around the room, swiping at his head and neck with the weapon before the incident was broken up by a dog handler.

Dolan's injuries were limited to a 'small nick' to the back of his neck.

Waling with the aid of crutches in court having suffered a broken leg in prison and wearing a grey Adidas jumper, Johnson was serving a lengthy sentence at the time of the offence - having been convicted of robbery, attempted robbery, possession of an imitation firearm and fraud in 2016.

He admitted possession of a bladed article in a prison and breaching a non-molestation order – having sent a letter to his former girlfriend in December 2018, which he had been banned from doing so by Manchester Family Court.

Johnson managed to circumvent prison rules by getting a fellow inmate to send her the note, in which he said he would 'not stop contacting her' and referenced the attack on Dolan.

Having been due to be released in August 2020, judge Neil Flewitt extended his sentence by two years – and questioned why the Crown Prosecution had not charged him with a more serious offence.

Sentencing, judge Flewitt said: "Why on Earth has he not been charged with some form of assault?

"It's a strange decision.

"You were in possession of a very dangerous bladed article, capable of causing a serious injury.

"The reason you were carrying that weapon was a running dispute with a fellow prisoner, who you believed to have some sort of relationship with your former partner – you made a serious attempt to use the weapon to injure him.

"Happily, at most the injuries amounted to a small nick to his neck.

"You could and perhaps should have been charged with some sort of attempted assault, but you weren't.

"Possession a bladed article in custody is an extremely serious matter, and can often lead to very serious injury – as well as disrupting good order in prison."

Forfeiture and destruction of the weapon was ordered, with Johnson also told to pay a victim surcharge.
