A school bus driver has been suspended after a young boy was left for hours on a school bus near Lac La Biche.

The four-year-old boy was left on the bus after the morning run, said Northern Light School division officials.

The driver found him later in the afternoon almost seven hours later.

The driver has been taken off the job while they figure out what happened, said Cheryl Hunter with the school board.

"We're still in the investigation process," she said. "We should know more after we piece everything together and start making headway on that investigation."

It is school board policy to have drivers check all the seats after the kids have left, said Hunter.

The student is in good health, she said.
