Minneapolis Public Schools remain on "code yellow" lockdown Thursday morning
Someone anonymously threatened on Wednesday to open fire on an unspecified school.
An automated phone message was sent to parents last night, and this morning the district also added an update to its Web site notice:
As a precautionary measure, Minneapolis Public Schools will continue operating on a code yellow on March 11. The Minneapolis Police Department continues to investigate to determine the significance of the threat reported on March 10. We have no specific reason to believe that any one particular building has been linked to this reported threat.
As a reminder, in a code yellow, classroom instruction continues. Exterior doors are locked. Additional attention is paid to anyone entering the building. We will continue to keep you informed as we learn more.
Minneapolis police now say that the lockdown was triggered by the Facebook page of someone in Australia who hasn't been in the country for seven years. Someone saw that page and alerted MPD via its 311 line at about 7:30 a.m. Wednesday. By 9 a.m., the lockdown was in place and parents were notified by the district's automated phone message system.
Police say the person in Australia may not be behind the threat -- may not even know the threat was made. Today, the investigation will focus on who placed the 311 call to.
Cretin-Derham Hall, the Catholic high school in St. Paul, was the target of an e-mail threat yesterday also. The Pioneer Press is reporting that the e-mail appeared to come from a computer in the Netherlands.
The state Department of Public safety said two other threats posted on social networking sites came to light in the past month. Simley High School in Inver Grove Heights received online threats of a potential shooting at a pep fest event. It was cancelled. Farmington High School also recently addressed rumors spread on Facebook of fights and a potential shooting. In both cases the threats were unfounded.
