There is tight security at Haslett High School this morning in Meridian Township after yet another bomb threat. The building has been locked down since 5 o'clock last night. This is the second bomb threat at the high school in less than a week. A note was written in the stall of a boys bathroom near a counseling office stating there would be a bomb Friday. Last Friday, there was another bomb threat. A text threat came in to the 911 call center in Alaiedon Township. Students were evacuated to the football field for about two hours while dogs searched the building. Nothing was found. Police say students' bags, backpacks, and any other items brought into the building today will be searched.
