Cork Support after Crime Services say young people often find it almost impossible to leave a life of crime behind after being attracted to it by a false sense of glamour.
The group based on Anglesea Street in the city say they have provided support to victims of random attacks carried out by young people.
They are calling for parents to know where their children are and say teenagers should have curfews.
Speaking to RedFM News, Sally Hanlon from Cork Support after Crime Services outlines one of the crimes young people have been involved in:
"Say they're walking alone in the park or sitting alone on the park - minding their own business - a group of them come around, maybe with a hurley or a weapon or a stick or something - and start to lay into you. They're not robbing you, they are not taking your phone - it's just for the craic - it's 'we can do this and get away with it' - that does leave victims in its wake. Now we have one particular young lad whose jaw was broken in three places".
