Kimmy Randall Bear, 24, surrendered to police who surrounded a house on the first nation 75 kilometres northwest of Prince Albert Thursday afternoon.
A CBC reporter who was on scene said at 1 p.m CST the officers had been calling out to Bear.
"They're saying 'Kimmy Bear, we know you're in the house. Come out the front door,'" Dan Kerslake reported.
After an hour and a half a number of officers calmly entered the house and walked out with Bear, who was placed in a waiting police vehicle. It seemed to be welcome news to a number of community members who were watching the action.
"As they brought him out the front door people started honking their horns and shouting, 'they have him, they have him,'" Kerslake said.
Many people on the Ahtahkakoop First Nation have been fearful since William Ahenakew and Trez Sparvier-Scott were found dead in a house that burned down early Monday morning in a suspicious fire.
A four-year-old girl who was rescued from the fire also received serious injuries.
On Wednesday, RCMP issued Canada-wide warrants on charges of second-degree murder and attempted murder for Bear, 25, and Carl Anthony Albert, 21, who are both from Ahtahkakoop.
A third man, Dominic Chase Ahenakew, 19, has been arrested and charged with two counts of second-degree murder. The RCMP says the victims and the accused were not related.
Police said they are still looking for Albert, who they believe to be staying somewhere on the Ahtahkakoop First Nation.
