In court documents obtained by People magazine, Tran states that the pop star "threatened to kill me, to take me out to others," "threatened to kill me over text messages," "threatened to harass my friends" and "threatened to shoot me."
"Around the second week of February, he told a few people that he was going to kill me," Tran says in her declaration that also requested her mother and brother be protected from Brown as well.
"He said if no one else can have me, then he's gonna 'take me out,'" she added.
The actress also shared in her sworn statement that during their relationship Brown had "punched me in my stomach twice," and "pushed me down the stairs."
One of Tran's friends was said to have been threatened by Brown when they ran into each other at a party as well.
Tran and Brown had dated on-and-off-again until their split in March of 2015.
Brown and his lawyer have yet to respond to the restraining order.
The rivals exchanged a number of jabs on social media including a collection of memes aimed at one another and agreed to face each other in a celebrity boxing match until Soulja Boy announced Monday on Twitter that the bout had been called off.
