Police have arrested Travis Chief, 23, for his alleged involvement in the death of 43-year-old Henry Kipling.
Kipling, a father of two from Peguis First Nation, was in town for a wedding social at the time of the attacks.
He was attacked twice by two different people last weekend at the Northern Hotel on Main Street in Winnipeg Feb. 27, police said.
The attacks started inside but eventually moved outdoors just after 2 a.m.
Keith Horn, manager of the hotel, said earlier this week he witnessed a woman "clothesline" Kipling in the bar.
Horn said he saw the woman slam Kipling to the ground, adding he witnessed Kipling hit his head on the ground following each assault by the woman.
Police said Kipling was helped to his feet by some people outside the hotel and the woman left the scene. About 30 minutes later, he was assaulted again and robbed by a male suspect, police said.
'Quietly waiting for a cab'
"The investigation has revealed that Kipling was quietly waiting for a cab when he was attacked and robbed," police said in a statement Saturday. "He was incapacitated at the time due to the earlier assault."
Kipling was eventually found outdoors near the hotel and taken to hospital. He died of his injuries.
Surveillance footage from the Northern Hotel was reviewed and on Wednesday, police released photos of suspects to the public.
Jenna Traverse, 23, was arrested March 3 and charged with aggravated assault due to her alleged involvement.
Chief was arrested in Waywayseecappo, Man., just before midnight Friday with the help of the Dakota Ojibway Police Service. He has been turned over to the Winnipeg Police Service and remains in custody.
Police have not said whether charges have been laid against Chief for his alleged involvement in the case.
