Frankston Crime Investigation Unit detectives are investigating following a theft and stabbing at a Frankston shopping mall on Saturday.
It’s believed two unknown females stole items from a store in Station Street, about 3.55pm.
As the pair attempted to leave the store they were confronted by staff and a struggle ensued.
The staff member was overpowered by one of the females and she was able to flee from the shop, chased by the staff member.
A nearby man saw the commotion and attempted to detain the female.
