Robert Louis Stevenson, Larry Larson Middle School and Grandview High School went into lockdown Wednesday morning.
The action comes following an armed robbery in the 1500 block of West Third Avenue. Columbus Police say two armed men entered this building and forced the employees inside to the ground.
They told workers there were bombs outside the building, but as of right now, no devices have been found.
All three of the buildings will remain on lockdown until they receive further notice from Grandview Heights Police Department.
The school district says it will contact families once they have removed the lockdown.
