Teen hospitalised on NSW Central Coast after alleged stabbing

A 15-year-old boy is in a critical but stable condition at Gosford Hospital, after he was allegedly stabbed at Terrigal on Friday night.

Officers with Brisbane Water Police District established a crime scene, and spoke with a number of teenagers, but no arrests have been made.

NSW Police has urged anyone with information, CCTV or dash-cam footage in the area to come forward.

A teenage boy has undergone surgery after he was allegedly stabbed at Terrigal on the NSW Central Coast on Friday night.

Emergency services were called to a home on Painters Lane about 9:45pm, with paramedics treating the 15-year-old for an alleged stab wound, before he was taken to Gosford Hospital in a critical condition.

Officers with Brisbane Water Police District set up a crime scene, with investigations focusing on two groups of teenagers that were reportedly in the area at the time.

"Those two groups met up in the Terrigal area; they appear to have gone to Painters Lane," Brisbane Water Police District, Detective Chief Inspector John Zdrilic said.

"The reason is unclear as to why they did that, and an incident has occurred which has resulted in the [alleged] stabbing of the 15-year-old male.

"The 15-year-old who was [allegedly] stabbed was there with two mates, and they met up with another group that could have numbered up to five."

Detective Chief Inspector Zdrilic said it is believed at this stage that there was no confrontation between the two groups in Painters Lane.

"[Police are investigating] one, the reason as to why they've gone into Painters Lane and, two, whether there's a previous relationship between these two groups," he said.

"The boy approached a home at Painters Lane to seek help, with residents calling 000.

"It appeared to be a single stab wound to the left side, heavy bleeding. [An] ambulance attended fairly quickly and he was conveyed to Gosford [Hospital]."

Brisbane Water Police District has established a strike force to investigate what led to the alleged stabbing.
