A teenage boy who stabbed a girl in a masked attack at a school will not give evidence during his trial, a court has heard.

Norfolk Police was called to Thorpe St Andrew School, near Norwich, on 11 March following reports a 15-year-old had been stabbed in the back.

The defendant, who is 16 and cannot be named for legal reasons, denies attempted murder, but has admitted possessing a kitchen knife without lawful authority and wounding with intent.

Stephen Rose KC, for the defence, confirmed to the jury that the boy would not be giving evidence at King's Lynn Crown Court.

The judge, Mr Justice Lickley, said the jury "may draw such inferences as appear proper from his failure to give" evidence.

In response, Rose said: "Yes, he has been advised."

The jury was previously told the then 15-year-old was captured on CCTV stabbing the schoolgirl, who described to police how she told a teacher: "Sir, I've been stabbed."

Steven Ball, prosecuting, read a number of agreed facts to the jury and brought the prosecution case to a close.

He told the jury that the kitchen knife used to stab the victim had a blade measuring 18cm (7in) and a handle measuring 12cm (4.7in) and was found in a wooded area.

The victim had a "2cm wound left of spine" and there were "no clinical signs of significant blood loss", he said.

He said the medical notes described the wound as "approx 4mm approx. 1cm unclear depth".

The jury also heard a note was found that said: "To my dearest mother I hope you are doing well."

It went on to ask about members of the family and said: "I understand you may hate me."

The court previously heard how the defendant had written notes saying he hated women.

The trial continues.
