A statement from the Los Angeles County District Attorney's Office claims that Yunyao Zhai, 20, was sentenced Wednesday to 13 years in state prison.
Zhai's co-defendant, 19-year-old Xinlei Zhang, will spend the next six years behind bars while a third defendant, Yuhan Yang, 19, received 10 years, the statement says.
On Jan. 5, Zhai, Zhang and Yang all pleaded no contest to felony counts of kidnapping and assault, the statement says.
According to prosecutors, Zhai and Zhang assaulted a 16-year-old girl on March 28, 2015, inside a park and a restaurant in California's Rowland Heights.

Zhai punched and slapped the victim during the attack.
Two days later, the trio kidnapped an 18-year-old girl and took her to a park, where she was stripped of her clothing, beaten, kicked and burned with lit cigarettes. The attack lasted five hours, according to authorities.
Using scissors, Zhang chopped off some of the victim's hair, and then forced the girl to eat it, prosecutors say.
Prior to Wednesday's sentencing, Los Angeles County Superior Court Judge Thomas C. Falls likened the three defendants' crimes to the classic book Lord of the Flies.
