Two students have been injured after projectiles hit four school buses leaving Daniel Hand High School on Friday.
Police said the buses were hit by what appears to be projectiles from a pellet gun around 2:20 p.m.
One window on one of the buses was damaged. Two students sustained minor injuries but did not require medical attention, the school said.
Students were brought home on a different bus, the school said.
The incident is being investigated by the Madison Police Department.
