Another state worker has been severely beaten by a resident of the Eldora Boys State Training School.

The Des Moines Register reports that the unidentified staff member had numerous teeth smashed out and suffered broken bones in his face.

Department of Human Services Director Jerry Foxhoven told his department’s advisory board that the assault occurred Saturday. The school is for boys whom courts have found to be delinquent because they committed crimes. Officials say that about six weeks ago four residents beat up another staff member during an escape attempt.
