MINNEAPOLIS (AP) - A high school in Minneapolis will be closed Wednesday after officials say they received a credible threat.

Principal Bill Smith said Tuesday night in a notification to the Southwest High School community that officials decided to close the following day to ensure the safety of students and staff. He said teachers are encouraging students to participate in discussions and complete work online during the closure.

Smith said all of the events, activities and practices scheduled Wednesday at Southwest High School are cancelled. He said school officials will provide updates as they become available.

All other schools within the Minneapolis Public Schools district will remain open.

The Minneapolis Police Department is investigating the threat. An official with the department couldn't immediately be reached early Wednesday.
