The 29-year-old model was granted a temporary restraining order against Kardashian on Monday after alleging the 30-year-old reality star was abusive, in addition to posting explicit photos of her online.
"Rob has been violent with me in the past," Blac Chyna wrote in court documents, according to the Los Angeles Times. She claimed Kardashian attacked her during an altercation at her home April 8.
"[He] grabbed my phone and punched me in the side knocking me to the ground where I landed on my hands and knees," the model said.
"I had difficulty walking after that," she added, according to Us Weekly. "I went to my bedroom and locked the door. Rob was so out of control that he broke the hinges off my door."
Blac Chyna also said Kardashian has threatened to "kill himself multiple times in text messages" since their split. The former couple, who share 8-month-old daughter Dream, broke up in December after getting engaged in April 2016.
"I would first and foremost like to thank the judge for granting me this restraining order to protect me and I am now just going to go back to co-parenting Dream," Blac Chyna told reporters after appearing in court Monday.
Blac Chyna said on Monday's episode of Good Morning America that she was "devastated" after Kardashian shared naked photos of her July 5 on Instagram. Kardashian posted the private pictures after accusing Blac Chyna of cheating.
