A 15-year-old boy has been sentenced to 4 years and three months in a youth detention centre after being found guilty of killing a man in Bristol.
The defendant, who cannot be named for legal reasons, attacked 39-year-old Darren Edgington in the St Pauls area of the city in June last year.
Mr Edgington died from a single stab wound.
The boy, who was 14 at the time, was convicted of manslaughter in December.
A mobile phone seized after the boy's arrest suggested he had attempted to buy two knives online last February.
He had also viewed news stories involving fatal stabbings, and had more than 600 pictures of knives stored on the phone.
The court heard during the boy's trial that he had got into an argument with Mr Edgington about a stolen bike outside a shop on Grosvenor Road.
The victim died from a stab wound to the chest about five minutes after their first meeting.
