A 17-year-old boy had his leg amputated following an "unprovoked" stabbing during a bank holiday trip to Barry Island, Newport Crown Court was told. The incident occurred in May 2026 when the teenager, who cannot be named due to his age, was with friends.

According to prosecutor Nuhu Gobir, the defendant, 19-year-old Idris Ahmed, attacked the victim after the teenager attempted to mediate a dispute between two groups. Ahmed, from Riverside, Cardiff, denies charges of grievous bodily harm with intent, inflicting grievous bodily harm, and possessing a knife.

The court heard that the victim and his friends were enjoying a sunny day on the beach, engaging in playful activities. Ahmed was also present with his own group. As the groups began to interact near a rocky area, tensions arose. Although the two groups initially shook hands, Ahmed allegedly returned moments later and stabbed the 17-year-old in the leg without warning.

Witnesses reported seeing Ahmed approach the victim from behind, retrieve a knife from his shorts, and carry out the stabbing. The victim, who did not see his attacker at the time, described the sensation as "like a punch" and immediately knew he had been stabbed. He later recalled seeing another man attacking a friend with a plastic shovel.

Following the stabbing, the teenager became pale and felt himself losing consciousness. Ahmed fled the scene, discarding the knife, an act witnessed by an eyewitness who later identified him. CCTV footage captured Ahmed fleeing the area.

The victim was airlifted to the University Hospital of Wales in Cardiff, where he underwent several transfusions. However, due to a lack of proper oxygen flow to the leg, a through-knee amputation was deemed necessary.

During questioning by police, Ahmed reportedly responded "no comment" to most inquiries but denied stabbing anyone or having any knowledge of the incident. The prosecution contends that Ahmed intentionally caused serious harm by stabbing the victim in a vital area with a dangerous weapon.

The trial is ongoing.
