A 16-year-old boy has been detained for life for murdering a fellow pupil at school.
Luke Walmsley, 14, was stabbed through the heart during a break in lessons at Birkbeck College in North Somercotes, Lincolnshire last November.
The teenager had told Nottingham Crown Court the killing was an accident and he had carried the knife to scare Luke.
The boy, who cannot be named for legal reasons, showed no emotion when a jury found him guilty of murder on Monday.
Mr Justice Goldring recommended that the boy should serve a minimum term of 12 years.
The court was told how the 16-year-old had been in trouble with the police on two previous occasions.
During the trial the court heard of a history of ill-feeling between Luke and the other boy.
Twenty one child witnesses were called, many of whom spoke of the boy making threats against Luke and brandishing a knife at school.
The jury deliberated for more than four hours before returning a verdict of guilty by a majority of 11 to one.
