Barry: Boy, 15, attempted to murder teenage girl, jury finds

Mr Greenwood told the court the boy arranged to meet the girl to buy a vape off her.

When asked why, he replied that the girl had spoken about his mother and he “wasn’t going to let it slide”.

At the time of the attack, the victim did not realise she had been stabbed, saying it felt like “she had been punched.”

It was only after she received a message from the boy saying “say something and you are dead” she realised what had happened.

A member of the public called the emergency services and the girl was taken to the University Hospital of Wales, Cardiff.

There they found a 4cm (1.5in) stab wound to the right side of her back. The right side of her abdomen and right groin was also tender to touch.

Further examination found her right kidney was displaced by the attack.

The boy, from Cardiff, was arrested by officers the day after the assault.

The court was shown CCTV of the brown-haired boy in a dark puffer jacket and blue jeans as he met the girl.

She wore a black hoodie with white logo at the station car park.

Before the attack, the victim said the boy was in a “highly agitated state”.

The footage showed them chatting, along with two friends, before the boy follows the girl and her friend into a lane near the station.

British Transport Police’s Det Con Daniel Murdoch said he then “struck (her) in the back with his right hand” before the footage showed him running with a friend into the night.

Det Con Murdoch told the jury the boy was wearing a glove on his right hand, which is shown on CCTV before the attack and after.

CCTV last captured the boy going through the ticket barriers at Cardiff Central and catching a train to Cwmbran – and exiting the station at 22:41 and walking off.

Judge Jeremy Jenkins said he was satisfied, given all the circumstances of the case and defendant’s background, that a hospital order was appropriate.
