Officials in the Columbus Independent School District, located west of Houston, received word of a threat on social media just before midnight Sunday, school authorities said in a message on the district's website.
"Columbus ISD takes the safety of our students and employees very seriously and it is our top priority," the message said. "This situation has been turned over to the local law enforcement authorities, and Columbus ISD will continue to cooperate with our local authorities. It is the hope of the Columbus Independent School District, that the person who made the threat is prosecuted to the fullest extent of the law."
Authorities have not said what kind of threat was made or which social media platform was used to convey it, KHOU reported.
