RANDOLPH — A call claiming there was a bomb inside Randolph Central School prompted the closure of the school Thursday.

In a message posted to its Facebook page, the district said the bomb threat was made at 7 a.m.

“Even though this call was most likely not credible, it is our protocol to treat every threat as credible, which is why the school was put on delay. Due to the amount of time it will take to sufficiently clear the campus working in conjunction with local law enforcement, the decision has been made to close school for the day.”

Students who were picked up by buses before the delay was announced are currently at the school.

“We apologize for any inconvenience this may have caused this morning, but as always the safety of our children is our number one priority, so we are making sure they are completely safe before resuming school.”

Members of the Cattaraugus County Sheriff’s Office and New York State Police searched the school Thursday morning. The Sheriff’s Office is currently investigating the threat.
