A schoolgirl who was stabbed by a masked fellow pupil at school described how she told a teacher "Sir, I've been stabbed" after the attack.

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

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

In a police interview played to the jury at King's Lynn Crown Court, the girl said she had been in "panic mode" and felt numb and weak.

Describing the attack, which took place in a corridor, she said she had seen a masked person dressed "head to toe in black, no school uniform whatsoever".

She said she turned away and it "felt like he touched me on the shoulder, then it felt like he punched me".

She said she "didn't know I was stabbed at this point" but after turning into a classroom, "I went 'Sir, I've been stabbed.'"

The girl said the school lockdown bell sounded and staff gave first aid.

Of the incident itself, she said that once she had opened the door, "I felt sharp pain shooting through my back, I went like that and it was blood all over my hands".

She said in the interview, carried out days after the incident: "I don't think it's hit me properly yet.

"It's just a bit of a shock."

Stephen Rose KC, for the defence, asked the girl, who gave evidence in court, whether she had had any issues with the boy. She said she had not.

She wiped tears from her eyes and asked for a break during her evidence.

Another female pupil at the school, who witnessed the attack, said in a video-recorded police interview that the boy "came up behind [the girl] and just stabbed her in the back near her shoulder".

She said she "didn't think he realised I was there until after he did it" and that she ran off and told a teacher.

Asked at what point she had first seen the knife, she said: "As he raised it."

The court has already been told that the defendant had written notes saying he hated women.

One note, which prosecutors said was found by police pinned to the wall of his bedroom, said: "My barren world... Hello. To all readers out there in the UK and perhaps even the world. If you're reading this, I am either dead or in custody.

"I imagine the police will be the first to read this and seize it as evidence, so I will make something very clear. I made this decision to do so on my own."

Another note read: "Am I evil for that? Probably. Am I an incel? A misogynist? No. I just have good judgement."

Christopher Paxton KC, in opening the prosecution case, said: "We, the prosecution, say his intention is made plain not just by those moments of the stabbing, but made plain by his notes and his obsession with killing and being fuelled by hatred."

The trial continues.
