A state of Origin celebration turned sour on Wednesday night, when an argument between two men ended with one of them being stabbed.
A 29-year-old-man and a 34-year-old man, who live together in Mount Warrigal, went to a hotel to watch the rugby league match with friends, consuming an unconfirmed amount of alcohol, police said.
Lake Illawarra Police Inspector Andrew Koutsoufis said an argument erupted when they returned home, when the older man urinated in a floor drain in the bathroom.
They then entered the lounge room, and the younger man sat down. Afraid of being assaulted by the older man, he allegedly punched him in the face.
The younger man then noticed blood coming from his left forearm, the right side of his stomach and the back of his right thigh.
‘‘It appears during the altercation he was stabbed, but he only noticed when he went down,’’ Insp Koutsoufis said.
The injured man was taken to Shellharbour Hospital, where he had surgery on his arm for nerve damage.
The older man contacted Lake Illawarra Police at about 12.30am on Thursday, informing them of the younger man's injuries.
He was taken into custody, but officers could not speak to him overnight because of his level of drunkenness.
He has since been charged with reckless wounding. His bail was refused and he will appear in Wollongong Local Court on Thursday.
