At least two schools in Chautauqua County report being on the receiving end of a “swatting” phone call Thursday.

Jamestown Public Schools went into a lockout due to the message, which reportedly came through to the county’s 911 dispatch center in Mayville in the early afternoon. Silver Creek Central School said it secured all its buildings and went into a shelter in place.

As noted by the Associated Press, a spate of threats and false reports of shooters have been pouring into schools and colleges across the country for months, raising concerns among law enforcement and elected leaders.

Schools in New York and Pennsylvania were the latest targeted by so-called swatting. Computer-generated calls on Wednesday and Thursday made claims about active shooters, but it was all a hoax. One day earlier, nearly 30 Massachusetts schools received fake threats.

“As a result of a state-wide hoax being perpetuated across all counties in New York, hundreds of school districts have received false swatting calls,” the Jamestown Public Schools District said Thursday in a statement. “There has been no evidence that these calls are founded. Out of an abundance of caution, all JPS schools have been placed on a lockout this afternoon. During a lockout, no one can leave or enter buildings. Instruction will continue as normal. JPS will send more information as it becomes available.”

Silver Creek released the following around noon: “Approximately 40 minutes ago a 911 call came into Mayville dispatch that there was an active shooter in Silver Creek and Jamestown. Evidently, these types of “prank calls” are occurring in all four counties and across the state. Yesterday there were similar ‘prank’ calls placed in Pennsylvania. After learning about the call, our SRO, along with other law enforcement and administration cleared the buildings and grounds. We secured all entrances and went into a shelter and place. Once law enforcement confirmed that there was no credible threat, we lifted the shelter in place and resumed normal activity.”
