WAUKESHA, Wisc (WSAU)  Students at Kettle Moraine High School are off until Friday after somebody wrote that a bomb would go off at the Waukesha County school today. Officials said the threat was specific to the high school, and no other schools were mentioned – although youngsters at Wales Elementary also have the day off as a precaution. All extra-curricular activities at both schools were canceled for last night and today.

High school principal Jeff Walters said bomb-sniffing dogs had planned to check the building last evening. School officials and Waukesha County sheriff’s deputies secured the school after yesterday’s classes ended. Walters says the bomb threat is not deemed to be credible – but he said precautions needed to be taken in the aftermath of the Connecticut school shootings, and the move toward heightened security.
