Four people are in custody following an incident at Grapevine High School yesterday. The campus was put on lockdown following reports of a gun at the school. Fox Four reports a Snapchat image of a person with a gun in his waistband at the school spread among students, prompting the lockdown. The gun was found by officers, who say they knew who they were looking for thanks to the Snapchat photo. Police say three of the four arrested were students, who officials say are facing charges ranging from making a terroristic threat to possession of a firearm to possession of marijuana. Authorities are investigating if the gun was part of some type of plot at the school.
