All Minneapolis public schools were put on lockdown today as Minneapolis police responded to threats posted online.
MinnPost.com reports that threats did not target any individual school, so the entire district was locked down and all people entering and leaving buildings were checked.
Threats also prompted a partial lockdown at Cretin-Derham High School in St. Paul, and Minneapolis police believe they likely came from the same source.
Minneapolis schools were officially put into "code yellow," meaning classes would continue as normal, but security would be heightened, according to the Twin Cities Pioneer Press.
Someone had apparently threatened to open fire at a Minneapolis school, then shoot themselves, KARE-11 reports.
UPDATE: MPR News reports all students have been dismissed for the day but police continue to investigate the threats.
