Oconto Falls High School went into a brief lockdown Wednesday morning as a precaution after a suspicious person was seen carrying a large case.

“It looked like a guitar case and this was done as a precaution,” said Superintendent Dave Polashek. He was a student of the alternative high and was walking between the high school and alternative school.

The lockdown last only a few minutes until police verified it was not a threat.
