Three people are being banished this week from one of the six communities that make up the Lac La Ronge Indian Band — although the band isn't saying exactly why.

Banishment is a long-held practice, according to Lac La Ronge chief Tammy Cook-Searson, who provided few details about the people being evicted.

"They are acting in a manner that you know goes against community wishes, but I can't say any more," she said.

A banishment order can be made for a number of reasons, including threatening behaviour or repeated criminal activity, she said.

The request for banishment is made by a community member then voted on by council, she said.

Cook-Searson said she won't be releasing the names of the people or any further details on the cases.

Banishments usually last one year.
