Officials say seven students aboard a school bus that rolled on a rural road in southeast Nebraska have returned to school.

The accident occurred Friday morning about six miles south-southeast of Adams.

Freeman Public Schools Superintendent Randy Page says the students ranged from second grade to seventh grade. He says none was seriously hurt, so emergency crews weren't called and the students were sent home with their parents.

He says that in hindsight, the district should have had the children medically screened before releasing them.

Page says the bus was on a minimum maintenance rural road when it began sliding into a roadside ditch and rolling onto one of its sides.
