The teen from Oxford pleaded guilty to one count of grievous bodily harm without intent
The boy, who cannot be named for legal reasons, returned to at Oxford Youth Court for sentencing after a hearing on 19 August.
The teen was sentenced to a one year training and detention order in a young offenders’ institution.
He was also given a five-year restraining order not to contact the victim or visit any address he knows or believes the victim to be living at.
On 14 June police and the South Central Ambulance Service located a 14 year old boy, who had been stabbed near Coltsfoot Square.
The victim had been stabbed in nearby Samphire Road.
Investigating officer Detective Inspector James Mather of Oxford CID said: “This was a violent incident that resulted in a 14-year-old boy suffering stab wounds.
“Thankfully, due to the expertise of medical professionals, the boy survived his injuries and is recovering.
“The boy responsible for this stabbing has now been convicted and sentenced accordingly.
“This incident, quite naturally, caused great concern in the local community, but our officers responded quickly to bring the perpetrator into custody.
“Knife carrying will not be tolerated and such offenders will be robustly targeted, arrested, and put before the courts.
“The impact of carrying a knife can be enormous, both on the victim, but also on the perpetrator, who themselves are also at great risk by carrying a weapon.
“We ask for our local communities to help Thames Valley Police in the tackling of knife-enabled crime.
