A wave of fake reports of shootings sent several Minnesota schools into lockdown Wednesday, authorities said.
The Minnesota Bureau of Criminal Apprehensions (BCA) said the hoax calls were reported in more than a dozen districts, including schools in Minneapolis, St. Paul.
The calls also were reported in Rochester, Mankato, Austin, St. Cloud, New Ulm, Fairmont, Alexandria, Fergus Falls, Brainerd, Grand Rapids, International Falls, Bemidji and Cloquet. On Wednesday evening, a bomb threat was called into Coffman Memorial Union at the University of Minnesota, although the BCA said Thursday that it though that incident was unrelated.
"Given that number, I wouldn't doubt there's even more than that," BCA Superintendent Drew Evans said. Rosemount school district was the target of a hoax call earlier in the week.
The calls claimed there was an active shooter or mass casualties in classrooms. All reports were similar in nature — they come from an internet-based phone number with an out-of-state area code. None was real.
After the calls, local police in each district searched the schools. Meanwhile, school officials called or emailed parents informing them of the hoaxes and encouraging students to report any suspicious activity to law enforcement.
Minneapolis Public Schools officials said police searched Washburn High School after a hoax report of an active shooter. St. Paul police responded to a similar report shortly after noon at Johnson Senior High School, where they met with staff before sweeping the building. In St. Cloud, police searched Apollo High School.
About 10 a.m. in Rochester, a caller reported a man armed with a rifle was shooting people inside Lourdes High School. City police and Olmsted County deputies searched the Catholic school, where most students were in convocation at the time.
