Skaneateles Middle and High Schools were placed on lockdown just before 9 a.m. Thursday after a bullet was found inside the school, the district's office said.
The schools were no longer on lockdown as of 9:30 a.m., but were downgraded to a "shelter in place." That, too, was lifted as of about 1 p.m. and classes resumed for the rest of the afternoon.
The office said the Skaneateles Village Police Department is investigating the incident. The bullet was found on a middle school bathroom floor. The school district said a student has been identified as associated with the bullet, but it was not clear as of about 3 p.m. Thursday whether it was intended as a threat or was accidental.
The investigation Thursday included canine units, which swept the middle school and high school checking hallways, locker rooms and all open spaces as well as student backpacks. At that time, the middle school and high school remained in a "shelter-in-place status" while the elementary school was in a "lockout," meaning no one could enter or leave the building.
The school has sent out emails, text messages and phone calls to parents, updating them on the situation. The school district said it will release a statement on its website and social media pages later Thursday.
