A prisoner who laughed about "slashing up" another inmate has had his time behind bars extended.

Wesley Johnson, of Oswald Road in Manchester, appeared at Caernarfon Crown Court via video link from HMP Berwyn on Wednesday morning for sentence.

The 26-year-old had admitted offences of unlawful wounding and possession of an offensive weapon at a previous hearing.

David Mainstone, prosecuting, told the court that the offences took place on October 17, 2022, when Johnson was a prisoner at Berwyn.

At around 2pm, he and another inmate named Carl Jardine were in the education block when an argument took place between them.

They'd been "beckoning each other to the toilets for a fight," and when Jardine was about to leave the defendant told him: "Your missus will get a visit tonight."

A fight between them ensued and when officers arrived, Jardine had his hands up.

Johnson was making "slashing motions" at him with a blue-handled item.

The item was dropped when officers drew their batons, and on closer inspection it turned out to be a plastic toothbrush handle with a razor blade attached.

"This isn't finished," Johnson shouted - before laughing: "I've slashed him up."

Jardine sustained a four to six inch wound to his arm, which was glued, and refused to help police with the investigation into the incident.

However, the fight was caught on CCTV - footage of which was played to the court.

Mr Mainstone said Johnson had an "extremely violent" background, illustrated by his record of 30 convictions for 58 previous offences. Nineteen of those crimes were for violence, with offences including; battery, racially aggravated assault, affray, robbery and possession of a bladed article.

Gareth Bellis, defending, told the court: "The best mitigation this defendant has is his guilty pleas.

"While there is some exchange of words between the complainant and the defendant, in my submission it was the defendant who was attacked first by the complainant."

Mr Bellis said there had been "some element" of self defence at the start, but conceded that once the weapon had been taken out, it could only be viewed as "excessive self defence in all the circumstances."

"It is accepted on his behalf that he has an exceptionally bad record," he added.

The Leader:

"The defendant knows he is going to receive an immediate sentence of imprisonment."

Judge Timothy Petts said violence in prison, particularly involving the use of a "makeshift weapon" in Johnson's case, had to be treated seriously.

He said despite the fact there may have been an element of self defence at one stage, it was outweighed by his actions in carrying and using the weapon.

In total, Johnson received an 18 month custodial term.
