A teenager told a senior teacher "you know I can't control it" before he gave up his knife after stabbing another student to death, a jury has heard.
Assistant headteacher Morgan Davis described the aftermath of the stabbing of 15-year-old Harvey Willgoose at All Saints Catholic High School, Sheffield, in a video statement played to a jury at the city's crown court on Wednesday.
Mr Davis explained how he was about start his lunch time duty on February 3 when a group of boys told him that "(the defendant) has stabbed Harvey", saying they were "obviously in shock".
The assistant head said he ran towards the main school building, adding: "I could see to my right that Harvey was on the floor in the courtyard and there were some students around him.
"I then went into the main school building and turned right on the central corridor. As I did that I could see (the defendant) holding a knife."
Mr Davis said the student was "waving that around", demonstrating to the officers in the recording.
He said two female colleagues approached the teenager, trying to get him to drop the weapon.
Mr Davis told the officers: "He didn't look like he was going to drop it so I approached and put my hand out.
"And I said 'just give me the knife, just give me the knife.
"I kept repeating that in a kind of calm tone.
"At that point he told me 'you know I can't control it' or words to that effect."
He said that, after that, he "essentially took the knife from his hand".
The jury has been shown CCTV footage of Harvey being stabbed in the courtyard.
The court has heard that the defendant, who cannot be named, has admitted manslaughter but denies murder.
He has also admitted possession of a knife on school premises.
