A threat was called into Colleyville Heritage High School on Friday, prompting a response from the school district. As a result, several schools in the Grapevine-Colleyville ISD were placed on a secure protocol, including Colleyville Heritage High School, Heritage Elementary, and others. During this time, students and staff remained inside the buildings and continued with their normal activities, but exterior doors were locked and visitors were not allowed to enter.

The district has stated that the threat was ultimately found to be unsubstantiated. Further details about the incident are available from the school district, including a statement from the principal of Colleyville Heritage High School.
