Peninsula High School was placed on lockdown for a half hour this morning after school authorities received word from students that one student might have a weapon on campus, according to a message sent by school principal Tim Winter to parents.
Winter said school officials received the report at 8:25 a.m.
"By 8:30 a.m., our resource officer had the student in custody and the situation under control," Winter's message said.
He told parents that the school was placed on "modified lockdown" as a precaution. That means instruction continues, but no staff or students are allowed in hallways. Shortly after 9 a.m., the modified lockdown was lifted.
The News Tribune has contacted the Pierce County Sheriff's Department seeking more information.
