(CNN) -- Violence marred Black Friday shopping in at least seven states, including California, where police say a woman doused fellow shoppers with pepper spray in a bid to cut to the head of the line.
The incident happened Thursday night at a Walmart in the Porter Ranch area of Los Angeles, said Officer Robert Chavira, a police spokesman.
About 15 people were exposed to the spray. Los Angeles firefighters treated them at the scene and no one required hospitalization, Chavira said.
The woman was trying to get an Xbox video game console, CNN affiliate KABC reported, citing police. She was able to pay for her purchases and leave the store before police arrived, Chavira said.
Incidents also occurred in South Carolina, North Carolina, Florida, New York, Alabama and Connecticut, with most of the reported incidents happening at or near Walmart stores.
Despite the reports, Walmart said the day's shopping frenzy has been remarkably safe for shoppers at its thousands of stores nationwide.
"There were a few unfortunate incidents but overall we have received very positive feedback from our customers," Walmart spokesman Greg Rossiter said.
In 2008, crowds of frantic Black Friday shoppers trampled a Walmart employee in New York as he and other workers tried to unlock the door at 5 a.m.
While no deaths were reported in this year's shopping, authorities said they handled fights, shootings and other incidents through the morning.
