A brutal biker who slashed his girlfriend’s arm with a knife and then enlisted his mother to sew up the deep wound he caused has been jailed for more than eight years.

Christopher Goetze left the woman in agony with a 15cm cut to her left arm.

The 32-year-old bully denied her medical treatment - and left it to his mum to stitch it, leaving his victim with nerve damage.

A judge told him: “What a way of treating another human being.”

Goetze, of High Street, Rochester, admitted unlawful wounding, assault causing actual bodily harm, two offences of possessing prohibited firearms and one of possessing a disguised firearm.

Maidstone Crown Court heard the victim, 32, suffered serious domestic violence during the short time she lived with him.

He was also accused of branding her by forcing the woman to have a tattoo across her chest stating “Property of Chris”.

He had told her it would “fix” their relationship.

But he was cleared of grievous bodily harm when the trial collapsed because she was too ill to continue giving evidence.

Goetze denied two charges of causing grievous bodily harm with intent, two of inflicting grievous bodily harm, one of wounding with intent, false imprisonment, making a threat to kill and assault by beating between July 30 and August 9 last year.

The prosecution offered no evidence on those charges and not guilty verdicts were directed by Judge Martin Joy.

He was sentenced to eight years and four months - five years for the firearms offences, two years for wounding and 16 months for actual bodily harm.

The victim claimed Goetze stabbed her in the thigh with a wallpaper scraper, threatened to set her on fire and struck her several times with a Samurai sword.

Goetze repeatedly punched her to the head and struck her on the back with the flat edge of the sword.

He slashed her arm during a row in which she attacked him with a knife.

The firearm offences involved possession of a 12-bore sawn-off shotgun, a converted 8mm pistol and a stungun disguised as a torch.

All were found in a rented garage following his arrest, along with a collection of knives and knuckledusters.

Prosecutor Sarah Campbell said the victim feared Goetze would kill her.

He first attacked her in July last year when he discovered she had returned to prostitution.
