Ailina Tsarnaeva, the sister of accused Boston Marathon bombers Dzokhar and Tamerlan Tsarnaev, surrendered to police on Wednesday.

According to The New York Post, the 23-year-old Tsarnaeva turned herself in at a Manhattan police precinct for allegedly threatening her boyfriend's ex-girlfriend

"I know people who can put a bomb on you,” Tsarnaeva allegedly said. 

She was charged with making a phone threat and aggravated harassment, according to the paper. Tsarnaeva's boyfriend, George Briones, is currently in the midst of a legal battle with his ex-girlfriend for custody of their children. The woman, who has not been named, reportedly alerted authorities after Tsarnaeva called her home in Harlem, New York on Wednesday.

Tsarnaeva lives with her sister, Bella Tsarnaeva in North Bergen, New Jersey, just outside of Manhattan, the Associated Press reported.

Her parents, who are originally from Chechnya, now live in Dagestan. Zubeidat Tsarnaeva, the children's mother, has maintained her sons' innocence. Tamerlan, 26, was killed in a shootout with police just days after the bombing and Dzokhar, 21, is currently awaiting trial in prison in Devens, Massachusetts.
