DENVER -- Several Broomfield High School students received threatening text messages Monday prompting officials to place the school on a lockdown for about an hour.

The students showed the message to a school resource officer, who reported the incident to the school principal. The school was put on lockdown at about 2 p.m. until about 3:10 p.m.

Broomfield police said Jayme Schmieding, 18, of Broomfield sent the messages. He was arrested about a mile from the school and placed in the Broomfield Police Department Detention Center, police said.

Police said Schmieding is not a student at BHS.

He will be charted with intimidation of a witness and interference of an education institution. Principal Ginger Ramsey said the students and staff were never in danger.

A lockout is less intense than a lockdown, police said. During a lockout, no one can enter or exit the school, but students and staff can still move from room to room in the building, he said. In a lockdown, students and staff would stay in their classrooms with the doors locked.
