Extra officers were on the Lewisville High School main campus Thursday morning.

Police said they do not believe there to be any active threats at the campus.

Sanders is charged with harassment and was booked Thursday afternoon at Lewisville Municipal Jail.  His bond was set at $5,000.

“The security of our schools and the protection of students is of utmost importance,” said Lewisville Police Chief Russ Kerbow. “This situation highlights the incredible working relationship with our school district and its security staff. When we are informed of potential threats, each of us takes the matter seriously and we want everyone to know that we investigate them fully. We expect the suspect to be prosecuted to the fullest extent of the law and have already been in touch with the Denton County Criminal District Attorney’s office.”
