Two men who escaped from a Regina penitentiary last month are back in custody.

Cody Dillon Keenatch, 19, and Preston Clarence Buffalocalf, 22, were arrested at a West Broadway apartment late Tuesday night.

Sources tell CTV News they had likely been staying in the building for a week.

The men were part of a group of six inmates who broke through a brick wall at the Regina Correctional Centre and escaped on Aug. 24.

Police put the apartment building under surveillance after receiving a tip the men were inside.

On Tuesday night Keenatch went outside to make a phone call and that's when officers nabbed him.

After the first arrest dozens of police cruisers surrounded the building, while the tactical support unit moved in to do a suite by suite search for Buffalocalf.

About an hour later they arrested him inside.

They also arrested a woman who described herself as Buffalocalf's cousin. She has not been charged, but it is believed the men were staying with her.

CTV News spoke with gang expert David Cyr.

He says family connections can go a long way in helping escapees elude police.

"This is one big family. When you're in a gang you're supported very heavily," he said. "There's a lot of back up there that will help you."

The two escapees still on the loose are Ryan John Agecoutay, 25, and Daniel Richard Wolfe, 32.

RCMP say the men are dangerous and possibly armed.

Wolfe, originally from The Pas, is considered one of the founding members of the infamous and violent Indian Posse gang based in Winnipeg.

He was in Regina awaiting trial on two counts of first degree murder and more counts of attempted murder.

However police say they're not getting any intelligence or tips that he is anywhere near the city.

That contrasts with the way the arrests were made Tuesday night.

Police say tips had started to build over the last couple of days, so they had a good idea Buffalocalf and Keenatch were in Winnipeg.
