When her friend, a 22-year-old woman, went to her aid, she was allegedly threatened with the knife and had her mobile phone taken during the altercation.

The injured woman was treated by paramedics for two stab wounds and taken to Manning Base Hospital before she was airlifted to John Hunter Hospital in a stable condition.
