Man critical after NSW alleged break-in

A NSW man is in a critical condition after he was allegedly detained by two men while trying to break into a home in Newcastle.

Police received reports of three men fighting at the home at around 3.30am on Saturday.

A 34-year-old man was found being detained by two other men.

He was unresponsive and taken to hospital in a critical condition.

One of the men detaining him, a 33-year-old, was taken to hospital with facial injuries and was later charged with recklessly inflicting grievous bodily harm.

"Investigations suggest the 34-year-old man had committed a break, enter and steal offence at the 33-year-old man's home prior to the altercation," a NSW Police spokesperson said.

A 32-year-old who was assisting in detaining the older man has not been charged.
