A man was taken to hospital suffering stab wounds after a fight in a carpark at Erina.
Emergency services were called to a shopping complex on Terrigal Dr just after 7.20pm on Monday, September 16, and found a 39-year-old man with injuries to the left side of his chest and left arm.
The man was treated at the scene by NSW Ambulance paramedics before being transported by Toll Ambulance rescue helicopter to Royal North Shore Hospital where he is reported to be in a stable condition.
Officers from Brisbane Water Police District have commenced inquiries into the incident, and have been told two men spoke to each other inside the complex shortly before walking to the carpark where one man was stabbed.
As inquiries continue, police are appealing for a man they believe can assist with the investigation to come forward.
He is described as being of Caucasian appearance, 175cm tall, with a muscular build, long dark hair which is shaved at the sides and was worn in a ponytail.
The man had tattoos on his right arm and when last seen was wearing long dark pants, black singlet, black shoes and had black coloured headphones around his neck.
Police advise any members of the public who know this man not to approach him but to instead call Triple Zero (000).
