5am: THE 17-year-old Ballina teen who allegedly attempted to abduct a five-year-old girl at knifepoint at Ballina Fair shopping centre on Friday afternoon has faced court and is now in Richmond Clinic.
The youth was arrested on Friday and taken to Ballina Police Station, where he was charged with: take or detain child with intent to remove from parental control; reckless wounding; armed with intent to commit indictable offence; face blackened or disguised with intent to commit indictable offence; shoplifting; assault occasioning actual bodily harm.
He was refused bail and appeared before Lismore Children's Court on Saturday where an order for a mental health assessment was made by the magistrate under section 33 of the Mental Health Act.
Police said the teen is now under the care of Richmond Clinic and at this stage they have not set any future court appearances for the youth.
In a statement released to the media, police said they have been told the teen walked into a supermarket on Friday and allegedly stole a knife, before leaving the store and walking to a children's ride where a five-year-old girl was playing.
It is alleged the youth took hold of the girl's arm and dragged her away from her mother and siblings, while holding the knife out in front of him.
Police have told The Northern Star they believe the child was chosen at random, and the girl is unrelated to the youth.
A number of people intervened, asking for him to let the girl go and at this stage she managed to break free, and a 32-year-old man attempted to apprehend the teen.
A brief struggle allegedly ensued, in which the 32-year-old suffered a small stab wound to his hand, and hit his head on a shop counter, causing a large head wound.
The man was assisted by a number of other shoppers who disarmed the youth and held him until police arrived.
