More from CNN:

Massive brawls and food-court fights played out at more than a dozen malls across the country in what proved to be a chaotic day after Christmas.

Some of the mayhem was captured on social media. The chaos prevented some shoppers from grabbing clothes off clearance racks and returning gifts.

The mall incidents, which ranged from minor melees to mass evacuations, occurred from Colorado to Tennessee and Texas to New Jersey.

Police in some cities are investigating the role social media may have played in organizing the disturbances. The motive behind the mall brawls is not yet known.
