SALEM, Mo. (KSDK) - Salem, Mo. authorities are investigating an allegation that a kindergarten student was forced to drink urine on a school bus.

District officials say last Tuesday a fourth grade student talked a kindergartener into taking a sip of a liquid in a cup.

They say the liquid was urine.

The older boy has been suspended; officials say the younger boy is okay.

Schools superintendent Steve Carvajal called the incident a thoughtless prank.

"We don't tolerate anything like that, wouldn't matter what the age was. So, once again, we handled things quickly and justly because we want all kids in our district to be safe and free from anything like that," he said.

The incident is being investigated by the Juvenile Division of the Crawford County Sheriff's Department.
