SHERMAN, Texas (KTEN) — Two Sherman High School students have been arrested for their alleged involvement in making a false threat earlier this week.

The Sherman Independent School District said a female caller dialed the central office on Wednesday afternoon to claim that her son was on the way to the high school intending to "harm the campus."

That led administrators to lock down the campus and its perimeter as Sherman police, county deputies, state troopers and the district's own police force were on alert for any potential intruder.

Two unnamed students were identified in a follow-up investigation of the threat and both have been arrested and charged with making a terroristic threat, a third degree felony punishable by a fine up to $10,000 and a prison term of up to 10 years.

“We take threats of all kinds very seriously, and the safety of our schools is our top priority,” said Sherman ISD Superintendent Dr. Tyson Bennett in a written statement. “Though the Sherman High School campus was never in danger, Sherman ISD supports the full prosecution of any individual that threatens harm to our students, staff, and campuses.”
