A homeowner has bashed and detained an intruder with a golf club in southern New South Wales.

At about 1am on Sunday, the 21-year-old resident confronted two men who had allegedly smashed a window and were trying to break into his home at Koorawatha.

The man armed himself with a golf club and hit one of the intruders in the head, leaving him with serious facial injuries.

He restrained him until police and paramedics arrived.

The 42-year-old home invader was taken to Cowra Hospital before being airlifted to Sydney in a serious but stable condition.

The second intruder, a 59-year-old man, ran away but was arrested at a hotel in Koorawatha later that morning.

He’s been charged and will face court today.

The 21-year-old home occupant has been spoken to by police but it’s unclear whether he’ll be charged.

It’s believed he knew the men who broke into his home.
