Los Angeles ( CNN ) -- A southern California woman turned herself in to authorities as the person who pepper sprayed video-game shoppers in a Walmart during Black Friday 's shopping frenzy , Los Angeles police said Saturday . The woman has not been charged because detectives are continuing their investigation into the incident that required firefighters to treat 10 people for exposure to pepper spray , authorities said . The woman 's name was n't released Saturday , police said . `` We have her identity and we know who she is and where she is at . When appropriate action needs to be taken , we know where to find her , '' said Officer Bruce Borihanh , a police spokesman . `` She 's a suspect , but she 's not booked or anything , so we 're not releasing her name . `` The detectives have a lot to do . They have to interview a bunch of witnesses , the victims themselves , and from there they will determine what action needs to be taken , '' Borihanh said . The woman turned herself in Friday night at the Los Angeles Police Department 's Devonshire station in Northridge , California , Borihanh said . The pepper-spraying incident , which occurred in a Walmart in the nearby Los Angeles neighborhood of Porter Ranch , occurred Thursday night . Borihanh said he did n't have information explaining why the woman took about 24 hours to turn herself in . Black Friday shopping was marked by violence in at least seven states , including California . At the Walmart in Porter Ranch , the pepper-spraying incident occurred when a woman doused fellow shoppers with the spray as people were grabbing for Xbox video game consoles , police said . The suspect was able to pay for her purchases and leave the store before police arrived , authorities said . On Friday afternoon , police described her as a Hispanic woman , 32 to 38 years of age , 5-foot-3 , 140 pounds and wearing black pants and a black sweater . Police said Friday that the woman 's action did n't appear to be self-defense and that charges such as spraying a caustic compound would be determined later . One witness to the incident , Juan Castro , said he and other shoppers were hunting for `` deals , '' when a woman began using pepper spray . He was trying to buy a Wii video game at $ 20 , marked down from a typical $ 60 , he said . `` I do n't know if she felt threatened or she felt she had to do that to get what she wanted , '' Castro told CNN on Friday . `` I did n't see her personally , but I sure got the scent of the mace . I got it in my throat . It was burning . I saw people around me , they got it really bad . As you see in the video , some woman was crying 'my eyes , my eyes , ' '' Castro said . `` I tried to get away as quickly as possible because I did n't think it was worth it . No deal 's worth that , '' he said . Violent 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 had 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. CNN 's Sandra Endo and Michael Cary contributed to this report .
