Bethel Middle school was put into a modified lockdown this morning, after shell casings from a 22-caliber firearm were found outside a cafeteria door.
In a written statement Superintendent Kevin Smith said a student brought the shell casings to school, and there was no evidence of a credible threat.
The lockdown was lifted about 11:15 in the morning.
Police with a dog, and school officials searched the school. Students in the cafeteria were questioned.
Education officials say all students are safe.
The superintendent sent a message to parents explaining the situation, and saying “In the wake of the Newtown Massacre, our world has changed. Providing a safe school climate is paramount.”
Smith asked parents to “be cognizant of the kinds of things students bring in backpacks or pockets. Shell casings were clearly inappropriate.”
