The sister of the infamous Boston Marathon bombing suspects was arrested Wednesday after she allegedly threatened to "put a bomb" on her boyfriend's ex-girlfriend.

Aliana Tsarnaev, the sister of Dzhokhar and Tamerlan Tsarnaev, was charged with aggravated harassment after she turned herself in at the 30th Precinct stationhouse in Harlem, New York. According to the New York Police Department, the 23-year-old North Bergen, New Jersey resident was taken into custody at 2:30 p.m., the Wall Street Journal reports. She was then reportedly questioned, charged and released after receiving a summons to appear in court on Sept. 30.

The alleged victim, who lives in Harlem and has children with Tsarnaev's boyfriend, told cops that she and Tsarnaev have an ongoing feud and that Tsarnaev threatened her over the phone on Monday, a police source told the New York Daily News.

"I have people who can go up there and put a bomb on you," Tsarnaev allegedly told the victim, according to the source.

Tsarnaeva had another run in with the law in 2010 when she was entangled with a counterfeiting investigation. She was accused of picking up someone who was caught using a counterfeit bill at a restaurant in Boston, however prosecutors say that she "lied about certain salient facts during the investigation," reports the Associated Press.

As a result, she has been required to report to Massachusetts probation officers.

She has also lived in Cambridge, Massachausetts, at an apartment linked to her brothers, Dzhokhar and Tamerlan Tsarnaev, who are accused of planting bombs at the finish line of the 2013 Boston Marathon that killed three people and injured 264 others.

Dzhokhar has pleaded not guilty to the charges and will go to trial beginning on Nov. 3.

Their 26-year-old brother, Tamerlan, died during a shootout with police three days after the Boston bombing.

Aliana is reportedly currently living with her sister Bella Tsarnaeva.
