From the Celina Police:

At about 7:31 PM tonight, May 14th, 2025, Celina Police responded to a report that a man was possibly at Walmart and might have a bomb. The caller reported it to Walmart who then called us for assistance.

Celina Police were joined by the Mercer County Sheriff's Office and the Celina F.D. Walmart staff conducted a smooth evacuation, and they assisted Celina P.D. with a sweep of the building. 

No device was found, and Walmart was able to return to business in a short amount of time.

This call appears to be a hoax or swatting call. This incident remains under investigation.
