A shocking incident unfolded in a Cardiff suburb when a shirtless man brandishing a large knife menaced members of the public outside a local shop. The individual, identified as David Southwell, was captured on CCTV on August 18, 2024, outside Holmesdale mini market in Grangetown, running and lunging at passing cars while holding a knife. Southwell’s erratic behaviour prompted concerns from onlookers, leading to police intervention. Following this unsettling episode, Southwell targeted his former partner in Grangemoor park just two days later, assaulting the victim in a vicious manner.
During a sentencing hearing at Cardiff Crown Court, the prosecution detailed the disturbing events that took place. CCTV footage showed Southwell shirtless, wielding a substantial knife and making threatening gestures towards individuals on the street. The subsequent incident in the park involved Southwell chasing and physically attacking his ex-partner, causing significant distress and trauma to the victim. The victim experienced severe anxiety and panic attacks in the aftermath of the assault, requiring medical intervention to manage the mental health repercussions.
The court also learned that Southwell had a prior history of offending, having been on licence for a previous offence in 2022 at the time of the incidents in 2024. Despite pleading guilty to charges of actual bodily harm, possessing a bladed article in a public area, and using threatening behaviour, Southwell’s actions were deemed extremely serious. In response to his culpability, Southwell was sentenced to 18 months in prison by Recorder Andrew Hammond. The judge expressed concerns about Southwell’s compliance with the law, leading to a custodial sentence to ensure public safety.
Southwell’s defence counsel acknowledged his client’s remorse and early guilty plea, attributing his actions to a turbulent lifestyle and poor mental health exacerbated by homelessness. The defence portrayed Southwell as cooperative and regretful, emphasising his proactive behaviour while in custody. Despite these mitigating factors, the court deemed the offences grave enough to warrant a custodial sentence, given the impact on the victims and the broader community’s safety.
Following the sentencing, resources for victims of abuse were highlighted to ensure individuals in similar situations have access to support and assistance. Various helplines and organisations offering confidential aid and information were listed for those experiencing domestic abuse, violence, or stalking. By providing these crucial resources, authorities aim to empower victims to seek help and protection from abusive situations, promoting a safer and more supportive environment for all individuals affected by such incidents.
