Has anyone heard about odd police activities at walmart today?

Family anon in southern New Mexico said when they went to walmart it was closed with police at all entrances. They then went to another walmart and it was the same situation. They then decided to go check the 3rd walmart in town, and they also were closed with police at all the entrances.

Has any other anons heard about this? maybe other towns? Their town does get illegals so not sure if it is connected to that.
