PLYMOUTH — Plymouth High School Principal James Condon said police officers will be inside the school Friday as a precautionary measure.

The words came after Condon released information of a bomb threat at noon Friday at the school.

Condon said in a telephone interview Thursday afternoon that "we don’t have a need outside" for the police officers.

Officials determined a plan of action that also restricts the time students may enter the school Friday and by what doors.

Students will not be allowed to carry large carry-alls or backpacks into class.

Condon said no final exams are scheduled Friday, or any other activities which school authorities could link to a message written on a bathroom stall in the school that threatened a bomb "detonated at noon" Friday.

"There’s no relevance to this Friday," Condon said of the investigation into clues as to who would make the threat and why.

Police and school officials already have conducted a full search of the school, he said.

Condon spoke to students on the public address system Thursday morning about the situation. He is sending home letters to parents outlining safety precautions being taken.

Condon said he and his secretary have personally answered numerous inquiries from concerned parents Thursday to allay concerns.

He reiterated that students who have notes from their parents will be excused from attendance should they decide not to be in class Friday.

"We’re going to conduct business as usual," the principal said.

Teresa Smith, a mother of three boys, has a son who is a junior at the high school. Her thoughts were, initially at least, to keep her son home.

"I’ll probably let him stay home," she said, "for safety’s sake and peace of mind.

"But I’ll also get his input. He’s a junior, and he gets As and Bs, so I’m not worried about him missing. He’s almost an adult, so I’ll see what he’s thinking and how the kids are thinking about it."
