New video from a Walmart shopper shows the moment some rushed out of the store on Westpark at Highway 6.
Some parents grabbed onto their children as they evacuated.
"I kinda couldn't believe it was happening," a bystander said. "I was like, 'What if something happens right now? Where do I run to?' You never know if the bad person is right next to you."
A bomb threat was found to be not credible, but it changed the mood for shoppers. Some said they were immediately reminded of the recent shooting at a Walmart in El Paso.
SkyEye was over the scene, where a large group of employees in Walmart smocks were gathered outside, some distance away from the building.
Walmart released this statement to our sister station, ABC13 in Houston, Monday night:
"The safety and security of our customers and associates is a top priority. After being alerted to a potential threat, we notified local law enforcement, and evacuated the store out of an abundance of caution."
