Boy who stabbed girl at school was radicalised online, says father
Armed police officers were called to Thorpe St Andrew School after a teenage girl was stabbed by another pupil
Warning: The following report contains details that some may find distressing
The father of a teenager who tried to kill a fellow pupil in a school knife attack has described his devastation and belief that his son was "radicalised" by extreme material online.
The boy, now 16, was found guilty of attempted murder last week after a trial heard how he harboured a hatred of women, had a fascination with serial killers and had planned to target others in the attack at Thorpe St Andrew School, near Norwich.
Speaking exclusively to the BBC and calling for tighter controls, the boy's father said he did not want to "absolve" his son but suggested online material and "a culture of violence and horror" had influenced him.
The government said it was committed to ensuring all children were safe from radicalisation and threats online, pointing to its Prevent anti-terrorism scheme and the Online Safety Act, which compels social media platforms to remove and prevent the spread of illegal content.
The boy cannot be identified due to his age, and nor can witnesses and the victim in the case.
His father, who we are calling John, apologised to the 15-year-old girl injured in the attack on 11 March, saying: "We're so very sorry for what happened."
John spoke of his fears that young men were being radicalised towards violence and hatred.
"You can think... it can never happen to my family or my son couldn't be involved, but that's what we thought and that wasn't the case," he said.
