GRAFTON- Grafton Police say that students have returned to class at the high school there after not finding a suspicious device following a bomb threat.
The Milwaukee Bomb Squad responded to the scene.
Grafton Police say that at about 7:40 a.m., a school official discovered the threat in a first floor bathroom. Police and administrators suspect a threatening note left in a bathroom Tuesday may also be a homecoming hoax.
"It was written on stall. The note said 'this is a bomb threat. Detonation plus 12:33. good luck'. We took that to mean there might be a bomb in the building," says Joseph Gabrish of the Grafton Police Department.
A district staffer told Newsradio 620 WTMJ's Jay Sorgi that police took students to nearby St. Joseph's Church while authorities searched the building.
Police said no one was injured during the incident. They have begun an investigation into who made the threat.
Students say homecoming activities are in jeopardy.
"They try to find the one person, but everyone's getting punished for it," says sophomore Taylor Brace.
"It's a serious matter, it's not for a joke," believes sophomore Rajpal Kaur.
If someone gets caught, the penalties are no joke. The Ozaukee County district attorney says his office has prosecuted ten bomb scares in the last decade -- most of them school-related. The maximum penalty carries a three and half year prison term, and fines.
"We'll proceed expeditiously with trying to figure out who did this and then appropriate action will be taken," says Grafton Schools Superintendent Dr. Jeff Pechura.
