Authorities were on scene late into the night Monday after a note containing a bomb threat was discovered at Tahlequah High School.

Superintendent Lisa Presley said authorities believe the note was left in the school sometime after 3:10 p.m., when the normal school day had ended. Most students had gone home, but those who were left were immediately evacuated from the building, along with THS staff.

Law enforcement agencies including the Federal Bureau of Investigation, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and local and state agencies responded, as well as Tahlequah City Hospital EMS, Tahlequah Fire Department, and Tahlequah-Cherokee County Emergency Management.

Boys & Girls Club students who were on campus either caught rides from their parents or were transported to the nearby middle school to catch a bus. Roads around the campus were partially or completely blocked at different times throughout the evening.

Presley said “bomb-sniffing” dogs were called in and used to sweep the THS campus. Canines arrived and entered the facility to begin their sweeps at about 7:30 p.m. Monday. After a few hours, authorities had found no legitimate threat.

Police are continuing their investigation into who left the note, Presley said.

Shortly before 10 p.m., the district sent out a school messenger to notify staff and patrons about the issue, according to Presley.

“We want to let them know what happened today, and that everything was safe and secure,” said Presley.
