The school’s principal, Bill Smith, sent an urgent message to families around 11:30 p.m. Tuesday.

“This is an urgent message for families of Southwest. School will be closed tomorrow, Jan. 28, for students at Southwest because we received a credible threat to the school community,” Smith said in the message.

To ensure the safety of staff and students, they canceled classes so the building could be inspected.

The school called in the Minneapolis Police Department to walk through the building Wednesday morning and check for any unsafe materials.

The police said in a Facebook post that their response to the threat was standard procedure.
