A man is in a serious but stable condition after an alleged assault in Adelaide's nightlife district.
South Australian police were called to The Woolshed on Hindley Street just before 5am on Friday when a man was reported unconscious after an alleged assault.
The victim, a 27-year-old from Seaford Meadows, was taken to the Royal Adelaide Hospital.
Police arrested a 22-year-old Para Hills man at 10:30am.
He was charged late in the afternoon with assault causing harm.
He was released on police bail to appear in the Adelaide Magistrates Court in February.
