WICHITA (AP) — A Wichita elementary school was briefly evacuated after a student brought a fake hand grenade to school in his backpack.

School district spokeswoman Susan Arensman says the evacuation at Enders Open Magnet Elementary School happened Friday after a second student learned of the fake grenade and told a teacher.

Arensman told The Wichita Eagle in an email that police quickly determined the grenade was a fake. Students were back in class about 10 minutes after the school had a “fire drill” while the situation was being investigated.

Arensman says disciplinary action was taken against the student who brought the fake device to school.
