After responding to an incident at a house Monday morning on the Onion Lake Cree Nation, RCMP say they were responding to an assault complaint at a residence that involved nine different people.

All nine people, seven men and two women were arrested and taken into custody without incident, RCMP said in a series of Tuesday morning tweets.

Police said they are still investigating the incident, and asked "the public to please respect the boundaries police have in place so they can continue their ongoing investigation.

At approximately 5:50 p.m. CST Monday, RCMP began tweeting that they were responding to an incident at a house, warning people to stay away from the area. 

They said there was no risk to public safety. They also asked people who live in the area to stay inside their homes. 

The Onion Lake Cree Nation straddles the border between Alberta and Saskatchewan, about 50 kilometres north of Lloydminster.
