Swansea (The Wales Times) February 19, 2026 – A serial offender wounded his girlfriend just weeks after his release from prison for another serious assault, hurling her mobile phone at her head in a cocaine-fuelled rage, Cardiff Crown Court has heard. Thomas Jenkins, 28, from Oakford Place in Portmead, left a gash above her right eye, damaging the device in the process. The court was told the attack followed accusations of infidelity amid heavy drug and alcohol use.

What Triggered the Assault on His Girlfriend?

Prosecutor Matthew Murphy detailed how police became aware of an abandoned 999 call at 3.15am on January 30 from an address in Blaenymaes, Swansea. Officers attended promptly and spoke to Jenkins’ girlfriend, who bore a fresh cut above her right eye. She explained the wound was caused by Jenkins, who had been snorting cocaine—a class A drug—and drinking heavily that night.

As reported in coverage by The Wales Times, she told officers Jenkins had accused her of cheating before throwing the phone at her head with such force that the device itself was damaged. The police then proceeded upstairs to the bedroom, where Jenkins lay on the bed. He initially told them he had argued with his girlfriend but insisted it had been “resolved,” leading to his arrest on the spot.

How Did Jenkins Respond to Police Questioning?

In custody, Jenkins’ account shifted markedly. Shortly after 4am, he told an officer:

“I admit I threw my partner’s phone towards her and I am sorry.”

This admission came despite his girlfriend’s reluctance to see him charged. As noted by solicitor Giles Hayes in court, she did “in all probability” intend to continue their relationship, though she had been denied access to visit him while in custody.

Recorder Andrew Hammond, presiding over the case, reviewed police bodycam footage from the moment the girlfriend opened the front door. “It is quite obvious she is very distressed and in fear,” the judge observed, despite her lack of support for the prosecution. He described how she first whispered to officers that there was no problem, then gestured upstairs, appearing “clearly timid and afraid.” She eventually explained the incident before breaking down in their presence.

What Were Jenkins’ Charges and Criminal History?

Jenkins, a dad-of-one, pleaded guilty to inflicting grievous bodily harm (GBH) without intent, as well as possession of a small amount of cannabis discovered during his arrest. His record comprises 14 previous offences, including a GBH assault just eight months earlier that resulted in a nine-month prison sentence. That prior attack occurred before the latest incident, which took place while Jenkins was on licensed release from jail.

Court reports from The Wales Times also highlighted convictions for drug possession and driving offences among his history. Prosecutor Matthew Murphy outlined these details to underscore Jenkins’ pattern as a serial offender, having reoffended so soon after imprisonment.

What Mitigation Did the Defence Offer?

Solicitor Giles Hayes argued on Jenkins’ behalf that his client suffered from “poor thinking skills” and longstanding substance issues, which could be addressed through probation service intervention. The defence also raised Jenkins’ diagnosis of ADHD (attention deficit hyperactivity disorder), which had prevented him from maintaining employment. Hayes emphasised the support from Jenkins’ family as a positive factor.

Recorder Hammond acknowledged these elements, including the ADHD and familial backing. However, the judge stressed they did not outweigh the severity of the offence, particularly given its domestic nature and Jenkins’ history.

Why Did the Judge Impose an 18-Month Sentence?

In sentencing Jenkins to 18 months in prison, Recorder Hammond delivered a stern rebuke.

“Everything I’ve read about you suggests you think violence is normal or even excusable. It is a striking feature of how you conduct yourself generally,”

the judge stated. He underlined the court’s firm stance:

“This court takes a serious view of violence, especially domestic violence.”

Hammond warned Jenkins directly of his trajectory.

“You need to realise the path you are on leads ultimately to one destination, and that is prison.”

The bodycam evidence proved pivotal, vividly capturing the victim’s terror despite her later unwillingness to pursue charges. This footage, as described in court, showed her initial denial, fearful gestures, and eventual emotional collapse, painting a clear picture of coercion and harm.

Who Is Thomas Jenkins, and What Is Known About His Background?

Thomas Jenkins, aged 28 and residing at Oakford Place in Portmead, Swansea, is a father to one child. The court heard no further details on his employment, though his ADHD was cited as barring him from work. His 14 prior convictions paint a picture of repeated brushes with the law, spanning violent assaults, drugs, and motoring violations. The GBH from eight months prior—resulting in nine months’ imprisonment—directly preceded this offence, committed during his licensed release.

As a serial offender, Jenkins’ case exemplifies concerns over recidivism in domestic violence scenarios. Prosecutor Matthew Murphy’s account left no ambiguity: the attack stemmed from paranoia fuelled by cocaine and alcohol, with the phone thrown in blind rage.

What Role Did Drugs Play in the Incident?

Cocaine, a class A drug, featured centrally, with Jenkins snorting it heavily before the assault. His girlfriend confirmed this to arriving officers, linking it to his accusations of cheating. Cannabis possession compounded the charges, found on him post-arrest. Defence solicitor Giles Hayes flagged substance issues as treatable, yet Recorder Hammond deemed them insufficient to avert custody.

The cocaine frenzy not only incited the violence but amplified its ferocity—the phone’s damage attests to the throw’s power, splitting skin above her eye.

How Did the Victim React Throughout?

From the abandoned 999 call to bodycam interactions, the girlfriend’s fear dominated. Initially whispering denials and gesturing timidly upstairs, she later detailed the phone assault before crumbling. Despite this, she opposed charges and anticipates reconciliation, per Giles Hayes. Prison visit denials have separated them temporarily. Judge Hammond prioritised her evident distress over her stance, a common judicial approach in domestic cases.

What Broader Issues Does This Case Highlight?

This sentencing underscores judicial intolerance for domestic violence, especially from repeat offenders on licence. Recorder Hammond’s words—”violence is normal or even excusable” in Jenkins’ worldview—signal a need for rehabilitation beyond punishment. With ADHD, addiction, and “poor thinking skills” cited, probation was deemed viable yet secondary to incarceration. The 18-month term aims to disrupt his “path to prison,” though his girlfriend’s loyalty complicates deterrence.

Cardiff Crown Court’s handling reflects standard protocol: bodycam evidence trumps victim retraction, safeguarding vulnerable parties. As The Wales Times reported comprehensively, no detail—from the 3.15am call to the judge’s final admonition—escaped scrutiny.
