Whittlesea Crime Investigation Unit detectives have charged a teenage girl after two people were stabbed at a shipping centre in Epping last night.
Police were called to reports of a fight involving three girls at the High Street complex about 9.20pm.
A security guard attempted to stop the fight and was stabbed in the stomach by one of the girls.
Investigators have been told the girl then chased the other two teenagers and stabbed one of them several times before leaving the scene.
A 14-year-old girl and the security guard, a 19-year-old man from Lalor, were taken to hospital with serious injuries.
Investigators executed a search warrant at a residence in the Whittlesea area this morning where a 17-year-old girl was arrested.
She has subsequently been charged with intentionally cause serious injury, recklessly cause serious injury, recklessly cause injury, affray, assault with weapon and unlawful assault.
She will face a children's court at a later date.
