A 14-year-old girl who lured an autistic teenager to a park where he was stabbed to death has been jailed for three years.
Two 14-year-old boys were also sentenced to 13 years and 12 years respectively in a young offenders institution for the murder of Olly Stephens, 13, in Emmer Green, Reading, on January 3 this year.
Bike-mad Olly, who had autism, was 'ambushed' at Bugs Bottom field in Emmer Green on the afternoon of Sunday January 3 after he had apparently sought to defend another boy who was being humiliated in a group chat.
The two boys, now both aged 14, were convicted of murder following a trial, while a 14-year-old girl, who convinced Olly to go to the park as part of the set-up, pleaded guilty to manslaughter.
All three were sentenced on Friday and cannot be named for legal reasons.
Olly's attackers left him with stab wounds to the chest and back after a short scuffle at the scene.
The younger boy, who was 13 at the time, used a knife to stab Olly while the older boy was fighting with him, the trial at Reading Crown Court previously heard.

Jurors were told they had shared several messages on Snapchat in the days leading up to Olly's death, which demonstrated hostility towards him.
The girl said in one message to one of the defendants: 'Karma - he (Olly) deserves all of this.'
The older boy also said: 'I actually hate the kid with a passion - if I was to see him right now I'd probably end up killing him'.
The mother and father of the murdered schoolboy have urged the parents of teenage children to 'take their phones off them' after warning how social media 'played a massive part' in their son's death.
Stuart and Amanda Stephens said they remain 'broken' after the death of their 'generous, caring and loving' 13-year-old son in January this year, when he was lured to a park in Reading and fatally stabbed over an apparent online dispute with fellow schoolchildren.
Asked what words of advice they would offer to parents of children their son's age, Mr Stephens said: 'Take their phones off them and don't give them back.'
Mrs Stephens said she had 'no idea' at the time how badly her son was being treated by others.
She said: 'Keep asking questions, be suspicious, try not to be put off - you get batted away by your children, when you ask questions you don't get answers.
'Just keep going until you feel comfortable and trust your gut reactions as well.'
