A masked 15-year-old who was captured on CCTV stabbing a schoolgirl had written notes saying he hated women, a court has heard.
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.
The boy brought a knife to school, dressed in black with a face mask and had an “intention to kill”, prosecutors told King’s Lynn Crown Court.
Police were called to reports of the stabbing at 10:24 GMT, not long after parents had gathered at the gates.
Opening the prosecution case, Chris Paxton KC said the defendant armed himself with a kitchen knife and “went to school not to learn, but to kill”.
He was “dressed in black, masked up and tooled up”, jurors heard.
