Police were called to Sherwood Park Global Studies School on Friday morning after students saw the boy on the playground with the gun with an orange tip on the barrel.
Grand Rapids Schools spokesman John Helmholdt said district officials have repeatedly told students and parents about the school's "'zero-tolerance" policy regarding weapons and look-alike weapons. He said "even though this was a toy, it is considered a weapon" in the school's student policy handbook.
The boy is suspended for 10 days as the district moves forward with expulsion procedures. An investigation is ongoing.
