A student in New Haven confessed to making two threats that involved blowing up Wilbur Cross High School.
Wilfredo Gonzalez, 18, was arrested Monday morning, according to police.
Police said they were called to the school around 9:10 a.m. They said faculty, staff and students were evacuated to off-site warming shelters while an investigation was conducted.
The school was reopened about an hour and a half later, police said.
Gonzalez was arrested and charged with second-degree breach of peace.
He was also charged separately with interfering with a police officer after they said he fought with them during his detention.
Police said Gonzalez confessed to making the call as well as a similar one that prompted a police response on March 4.
An arrest warrant was being crafted for the earlier call.
