Ailiana Tsarnaeva was arrested in New York City on Wednesday after she threatened her boyfriend’s ex over the phone, allegedly threatening her with a bomb.

Ailiana Tsarnaeva Threatens Boyfriend's Ex

Ailiana, 23, the sister of Boston Marathon bombers Tamerlan Tsarnaeva and Dzhokhar Tsarnaeva, allegedly called her boyfriend’s ex at her Harlem home on Monday and told her to stay away from her boyfriend, George Briones. Briones is reportedly involved in a heated custody battle with his ex over their three children.

“Leave us alone. I know people who can put a bomb on you,” Ailiana reportedly told the other woman.

The woman Ailiana threatened immediately called the police, leading Ailiana to turn herself into the Harlem police on Wednesday. Ailiana has been charged with aggravated harassment and was released on bail. She will report to a Manhattan criminal court on Sept. 30.

Meanwhile, her younger brother, Dzhokhar Tsarnaev, 21, is currently awaiting trial in the Boston Bombing case and could face the death penalty.
