GATESVILLE, Texas (FOX 44) – UPDATE: An arrest has been made after a suspicious vehicle led to a brief lockdown within the Gatesville Independent School District on Thursday.

The district posted on social media and notified faculty and staff that some of the high school students were returning from their practicum. These students saw a suspicious vehicle parked in the parking lot blaring music with out-of-state plates and no parking ID.

As a precaution, the district placed all of its campuses “in Secure.” During the secure action, the district says all campus doors were locked and no one could leave or enter the buildings.

The district soon sent out another notification saying police apprehended the suspect, and the Secure lockdown was lifted for all campuses.

The Gatesville Police Department said on Thursday that its School Resource Officers received a call at approximately 10:45 a.m. regarding the suspicious vehicle. The department said the vehicle left the scene, and was not initially found. As other officers entered the area, the vehicle was found and a traffic stop was initiated.

During the initial investigation, the department says the identities of those involved were obtained and further investigation continues where at least one charge will be filed, with potentially more charges coming.

The department says no one was injured, and no direct threats were made. Police sent a “thank you” to the students who saw and reported the activity. The Coryell County Sheriff’s Office also assisted police.
