A University of California -- Riverside student has been arrested on suspicion of ordering her current boyfriend to murder her ex-boyfriend, according to jail and court records.

Barbara Wu, 21, allegedly told her boyfriend to kidnap her ex-boyfriend, break his legs with a baseball bat and kill him. But the boyfriend was cooperating with police and recording the conversation, according to a restraining order against Wu he filed after her May 29 arrest.

Wu faces charges of soliciting murder, stalking, online harassment, terrorist threats and other misdemeanor and felony crimes, according to the Riverside County Sheriff's Department. She was being held in a Riverside County jail on $500,000 bail.

The restraining order said Wu was abusive and impulsive, called him "her dog," and made him fear for his life. NBC4 is not naming the boyfriend.

"Barbara wanted me to get some people to kidnap her ex-boyfriend," he wrote in his petition for a restraining order. "She made me promise that I would go through with it. She wanted me to tie him up, use a bat to break his legs, kill him, then discard the body. She wanted us to leave the country after we did all this to him."

Neighbor Nicole Clark said Wu seemed like a regular college student, friendly and quiet.

Another neighbor, however, said she heard strange and loud noises coming from Wu's apartment.

"Screaming," said Maira Actual. "And you would just hear the noises of things being moved around."
