(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. Here's what happened at seven of those malls.
It all started with a social media post that promised a fight at the Town Center at Aurora.
Aurora Police Department spokesman Sgt. Chris Amsler said about 100 people had gathered in the food court before the brawls broke out -- prompting the Colorado mall to close early on Monday afternoon..
"(It) kind of morphed into this large disturbance," Amsler said.
When off-duty police officers working as security guards tried to break up a fight, people circled the officers, who called for backup, Amsler said.
As police officers on duty arrived, fights broke out throughout the mall, at a movie theater and at a nearby park-and-ride lot, he said.
He estimated 500 people were involved. Authorities arrested five people, all juveniles, and recovered no weapons, he said. One person assaulted at the park-and-ride lot suffered "significant" injuries and was taken to a hospital, Amsler said.
In Aurora, Illinois, seven juveniles were taking into custody Monday evening after police received a call for assistance at Fox Valley Mall "due to an unruly crowd in the common area," police said.
Moments after the call, a fight broke out in the food court area and those were followed by several other smaller altercations, police said.
The brawl forced evacuations and the mall closed. No injuries were reported in the incident.
In Memphis, Tennessee, seven people were arrested after incidents at two malls, CNN affiliate WMCA reported.
Police said a group started a disturbance in the Wolfchase Galleria food court and started running, which prompted some customers to call 911, WMCA said.
Then a crowd gathered outside Oak Court Mall, about 10 miles west, and started a disturbance, WMCA said. Both malls were cleared and closed early for the night.
Shots were reported in both incidents, but police said they found no evidence of gunfire, WMCA said.
No injuries were reported, CNN affiliate WATN said.
Fayetteville, North Carolina
In Fayetteville, North Carolina, people panicked after teenagers fought in the food court, Fayetteville police spokesman Shawn Strepay told CNN affiliate WRAL. No shots were fired, despite reports of gunfire, Strepay said.
"Once people start running in that area or chairs are getting knocked over, tables, that sort of thing, that echoes and it could resemble the sound of a gunshot to a lot of people," he said.
Elizabeth, New Jersey
The first calls from the The Mills at Jersey Gardens came in just after nightfall Monday. Witnesses said they thought they had heard shots fired. That, along with a fight, led to what Elizabeth police Officer Greg Jones described as a "chaotic panic and everybody running all at once."
Ultimately, though, patrons had mistaken the sound of a chair slammed during a fight for gunfire, city officials told CNN affiliate News 12 New Jersey. Two people, an 8-year-old and 12-year-old, were injured, the station reported.
Fort Worth, Texas
The security guards had no other choice but to place the Hulen Mall on lockdown. At one point, police told CNN affiliate KTVT, at least 100 people were involved in a series of fights.
Fort Worth Police spokeswoman Tamara Velle said officers initially responded to reported gunfire inside the mall. After breaking up the fights, officers stopped by each store to let people leave while the lockdown remained in effect, KTVT reported.
There were no reported injures or property damage -- thanks in large part to local police, Kelle said.
"You keep hearing the horror stories of the mall shootings across the nations right now," Velle told KTVT. "Anytime we're hearing about a mall shooting and it's the day after Christmas, (where) you have tons of people holiday shopping ... we're going to get in there as fast as we can."
Shortly after sunset, a large-scale disturbance broke out at Beachwood Place Mall, in Beachwood, Ohio.
An initial report of gunfire was quickly found to be false by police.
"One male juvenile was arrested for attempting to strike an officer that was dealing with another disorderly patron," Beachwood police said in a statement.
Beachwood police, officers from nearby jurisdictions and mall security were able to disperse the juveniles and remove them from the mall, police said in a statement. Beachwood Police Capt. Gary Haba told CNN that pepper spray was used to disperse a large crowd at one point.
The disturbance appears "to have been loosely organized on social media," the statement said.
Beachwood mall was re-opened and there were no injuries or other arrests.
