MAYVILLE — Three schools went into a brief lockout and three students taken for mental health evaluations Friday after threats of violence were reported, with two students reportedly threatening to bring guns to school. The threats come after 17 people were killed during a mass shooting at a high school in Florida, and resulted in a rebuke from local and state officials on the need for greater police presence at schools.

The names of the three teenagers, a 15-year-old student of Ashville BOCES, a 17-year-old of Randolph Academy and 17-year-old of Chautauqua Lake, were not released after they were taken into custody under the state’s mental hygiene law.

Capt. Eric Balon of the New York State Police said troopers and the state Bureau of Criminal Investigation responded around 9:05 a.m. Friday to Chautauqua Lake Central School in Mayville after a threat of violence was reported. A threat was also made to the Ashville BOCES and later Randolph Academy. It wasn’t immediately known if the threats were related.

All three schools went into a lockout as a result of the threats, Balon told reporters. An investigation led to the three students, at which time the lockouts ended.

“Both students were transported to hospitals for evaluation, and this investigation is continuing,” Balon said of the incidents in Chautauqua County.

In a statement on its website, the Chautauqua Lake Central School district said the verbal threat was received in the morning, prompting school officials to notify police and initiate the lockout.

“The threat was immediately identified and contained,” the district said. “Law enforcement investigated the matter and advised that the district could cancel the lock out and resume normal operating procedures. The lock out was a precautionary measure.”

BOCES also released the following statement:

“Earlier (Friday) our administration was made aware of a concern regarding statements made by students that have been investigated by law enforcement. “We instituted a shelter in place for our Hewes Campus, that has now been lifted. It has been determined that there was no credible threat and we are continuing to work with law enforcement on this matter.

“We appreciate your understanding, cooperation and support in keeping our students and campuses safe. Every concern has to be taken seriously when talking about school safety. Please be clear with your children: if you see or hear something say something.”

Friday’s events come days after 17 people were killed at a high school in Parkland, Fla. A 19-year-old former student, Nikolas Cruz, told police he opened fire at the school shortly after he was arrested.

In a statement, Gov. Andrew Cuomo said, “The school shooting in Florida continues to reverberate across the country. This morning, in two schools in Upstate New York, we had what appears to be ‘copycat’ threats made by students threatening violence and saying they would bring guns to schools.

“These two matters are under control. The schools involved were the Chautauqua Lake School District and the Randolph Academy in Cattaraugus County. Both students are in police custody. State Police are on site, and the schools are functioning once again after a brief closure this morning.
