A rifle bullet has missed a school bus driver in eastern Nebraska.

The Lincoln Journal Star reports that the driver was alone on the school bus about 8:25 a.m. Monday as it headed south on 238th Road, southeast of Seward.

Seward County Sheriff Joe Yocum says the bullet passed through the right side of the bus, struck a window frame and ended up on a seat near the center of the bus.

There haven’t been other reports of vehicles being shot at in the area, and Yocum says investigators don’t believe the bus was specifically targeted. He says all possibilities are being examined, however.
