Town of Chenango, NY (WBNG Binghamton) The Chenango Forks school district closed early Friday after someone broke into the high school overnight.
Superintendent Joe Peck says it happened sometime after midnight.
He made the call early to dismiss all 1,600 students in the district.
"Chenango Forks will always err on the side of caution and safety for its students," Peck said, "We are doing everything we possibly can do to make sure this doesn't happen again. We will have around the clock security from now on so this does not happen again."
On Friday morning, a Chenango Forks High School staff member noticed an unlocked door upon arriving to school.
Video surveillance was reviewed and showed an individual appearing to bring materials into the school and entering multiple classrooms.
New York State Police spent the morning searching the school.
No alarm sounded, although the district said there was no malfunction in the system.
The superintendent met with teachers and staff before the district was dismissed for the day before 10 a.m.
Authorities initially thought there was a suspicious package in the building. However, upon a complete search there was nothing found.
State Police say they are now focusing on who broke into the school.
