(KNZA)--A jury trial has been set for a Topeka teenager accused of making threats on social media that led to a lockdown at the Royal Valley High School last August.

19-year-old Braden Crowder stood mute during his arraignment Friday in Jackson County District Court, with his attorney entering not guilty pleas to a felony count of criminal threat and misdemeanor charge of telephone harassment

A two-day jury trial was set, beginning May 30.

The high school in Hoyt was placed on a “ modified lockdown” for several hours on August 29 after a series of alleged criminal threats over social media toward a group of students at the school.

Classes continued during the lockdown but all exterior doors remained locked.

The lockdown was lifted after Crowder was taken into custody later in the day in Topeka.

He remains free on a $25,000 bond.
