ConVal High School

ConVal High School, and all the schools in the Contoocook Valley Regional School District, were closed Wednesday after threats were made against students and staff.

ANTRIM — Police say three teens are behind the threats that led Contoocook Valley Regional School District suddenly cancel all classes Wednesday.

Anthony Wheeler, 18, with a last known address of Main Street in Antrim, was arrested Wednesday in Hillsborough, along with two other alleged accomplices. The accomplices are both under the age of 18 and their names are not being released at this time.

The arrests came in the hours after school district officials decided to cancel classes for the day. The cancellation happened around 6:30 a.m. Wednesday, as more than 100 students were on buses heading for the high school and middle school.

The threat was initially directed at the high school staff and students, according to ConVal officials.

Antrim police did not describe the nature of the threat, but said it was deemed serious by those who saw it. It was originally reported to police by a parent who saw the threat posted on social media.

“Some who saw the post were extremely alarmed and notified authorities,” according to a statement released by Antrim Police Chief Scott Lester.

Police executed search warrants on Wednesday, and Lester thanked Hillsborough police for securing some of the digital evidence. During the investigation police determined there is no ongoing threat, and schools throughout the district were open Thursday.
