BOERNE, Texas - Boerne High School was evacuated Wednesday morning after a threatening message claimed there were multiple bombs on campus.

Just before 8 a.m. on February 18th, a message was discovered on a school phone line indicating several explosive devices had been placed at the campus. At the time, students had not yet arrived for the day. The campus had not officially opened, and only staff members and a small number of students were present.

Officers responded immediately and began evacuating the campus while conducting a thorough search of the property.

With assistance from an FBI bomb technician and the San Antonio Police Department Bomb Unit, all buildings were carefully swept. Authorities reported that no credible threat was found, and the campus was cleared to reopen to students by 8:45 a.m.

Additional Boerne police officers remained on campus as a precaution.

Law enforcement agencies assisting in the response included the Texas Department of Public Safety, Boerne Fire Department, Kendall County Constables, Kendall County Sheriff’s Office, Kendall County Office of Emergency Management, Kendall County EMS, the FBI, and the San Antonio Police Department.

The investigation into the threat remains ongoing.
