Detective Inspector Emma Kerrigan said: “This was a frightening and reckless stabbing on a teenage boy who needed medical treatment, thankfully he did not sustain life threatening injuries.
“We received three different reports of assaults which took place on Cubbins Green on Friday night.
“I would urge anyone who was in the area who witnessed or filmed the stabbing or any of the assaults on your phone then please contact us so we can find those responsible and bring them to justice.
“The use of knives and any weapons is reckless and will not be tolerated, and has no place on our streets. Weapons such as this can have devastating consequences, not only for the victim and their family but also for the offenders involved.
“I would urge people to educate themselves and speak to their children and family members about the dangers of knife crime.”
