Two people took themselves to hospital with superficial injuries, believed to be from a stab wounds.

Senior Sergeant Trevor Smith spoke to 3AW Mornings with Neil Mitchell and said it was not a gang related incident, but the motivation behind the incident is not yet known.

“It looks like it was an arranged fight at the location with a group of 30 odd, mostly females, in their mid to late teens,” said Sargent Smith.

“When I was briefed this morning I was a surprised that majority of the people involved were female.

“Anybody who arranges fights like these or comes to these events are offenders.”

Most of the youths fled when police arrived.
