Two people were scheduled to appear in court this morning after an incident in Green Lake on the weekend.
RCMP were called to a home in the community on Saturday morning.
It was believed firearms were involved and the Emergency Response Team was brought to the scene.
Traffic on Highway 55 was also shut down.
Later on Saturday, police reported that three people had been arrested and one person remained at large.
Two of those suspects are facing firearms charges, while the third person was released.
RCMP say they are issuing a warrant for the other suspect who is still at large, and more information will be released later today.
