Police in several US states responded to reports of at least a dozen chaotic incidents at shopping malls on Monday, including melees involving hundreds of people and false alarms about gunfire.

The disturbances broke out on the post-Christmas shopping day as many stores reopened. This year, December 26 was observed as a federal holiday in the US as Christmas Day fell on a Sunday. While many retailers have taken on the tradition of Britain’s Boxing Day sales, it traditionally pales in comparison to the US shopping extravaganza that is Black Friday, the day after Thanksgiving.

Police departments across the country were alerted to several reports of gunshots and mass brawls at a number of shopping centers, forcing shoppers to evacuate and malls to close early.

The Mills at Jersey Gardens, Elizabeth, New Jersey

Up to 10 people were injured, including two children, when chaos broke out after the noise of a chair hitting the ground reportedly caused someone to shout “gun” in the mall.

The Mayor of Elizabeth took to Twitter confirming that no shots had been fired, but that a fight had broken out.

Armed police responded to the incident and evacuated the building.
