Officials arrested a 31-year-old woman Thursday for allegedly attacking a 13-year-old at a Los Angeles McDonald's in a now viral video.

The suspect, Ariana Lauifi, is being held in suspicion of a child abuse felony for the Sept. 6 attack in the Harbor City neighborhood, according to the Los Angeles Police Department.

"The public’s continued interest in the incident resulted in investigators receiving numerous leads, ultimately assisting detectives in positively identifying the suspect," LAPD wrote in a news release.

Cell phone video recordings show a woman brutally punching and kicking 13-year-old Kassidy Jones multiple times, pulling her hair and forcing her to the floor inside the fast-food restaurant as no bystanders interfere. Jones said she and her friends were walking home from school when they stopped at the restaurant to use the restroom, KTLA reported.

Jones said a woman she had never met before quickly lunged at her and began beating her. The child added the entire incident was completely unprovoked. She recalled the attacker saying "What the F are you looking at? I fight kids. I’ll fight you!"

The suspect is currently held with the bail price set for $100,000, jail records show. The case will be sent to the Los Angeles County District Attorney’s Office for filing consideration, LAPD said.

The victim suffered severe bruising including on her face, according ABC7. Jones' mother reportedly said her daughter is also hurting emotionally.

"She can't sleep at night. She's bruised," the victim's mother Angelina Gray told ABC7. "She doesn't want to go to school because she's tired of the kids and everybody asking her what happened and making fun of her."

"The family of Kassidy Jones are extremely grateful that the LAPD has made an arrest of the woman who viciously beat Kassidy in an unprovoked attack inside McDonald's. As McDonald's managers and onlookers offered no help in stopping the assault," a spokesperson for the family said in a statement.

"Kassidy, is still traumatized and undergoing therapy. But hopefully this news will give her encouragement that justice will be served. Kassidy deserves a break today."

“We were horrified to learn about this violent attack, and our thoughts are with Kassidy and her family," store owner and operator Tawnie Blade told USA TODAY. "Employees called police when the fight began, and we’re continuing to work closely with local law enforcement to help with their investigation."
