Bargain hunters <a href="http://www.monclersalestore.com">Moncler Sale</a>at a Walmart in Los Angeles were hurt when a fellow shopper attacked them with pepper spray as the doors opened on the US's holiday shopping season.
Authorities said the woman was trying to keep the other shoppers from merchandise she wanted during early opening on "Black Friday", the name given to the post-<a href="http://www.monclersalestore.com/12-moncler-coats-women">Moncler Coats Women</a>Thanksgiving shopping day.
"Somehow she was trying to use it to gain an upper hand," Police Lieutenant Abel Parga told the Associated Press. Authorities said the woman was "competitive shopping".
Officials said 20 people suffered injuries. Matthew Lopez, one of the shoppers, told: "I heard screaming and I heard yelling. Moments later, my throat stung. I was<a href="http://www.monclersalestore.com/8-moncler-hoodies-women">Moncler Hoodies Women</a> coughing really bad and watering up."
Parga said police were still looking for the woman. The store remained open and those not affected by the pepper spray continued shopping.
