According to police, a lockdown was lifted at all schools in the Hopkinsville school district, and a student was arrested.
The lockdown on Thursday was due to threats allegedly sent by text message to various students. The threat said a shooting was going to happen at the high school.
The initial lockdown was in place at Hopkinsville High School and Hopkinsville Middle School. Police said they cleared both schools, and students were safe.
Shortly after the search, police told the district to put every school on lockdown as a precaution.
They investigated the threat and discovered it was unfounded, lifting the lockdown.
Detectives said they interviewed 18-year-old Brandon D. Govan, and he reportedly admitted that he was responsible for the texts that he allegedly sent while at school.
He told police he sent the texts so he could be sent home from school.
The student was arrested and charged with third degree terroristic threatening. He was lodged in the Christian County Jail.
A second student, age 17, was also arrested and charged with tampering with physical evidence, second degree hindering prosecution, and second degree disorderly conduct. Police said the second student "became disruptive and combative when officers entered a classroom to speak with another student about the initial incident."
Further details were not available.
