Boston Marathon bombing suspect Dzhokhar Tsarnaev's sister has been arrested and accused of threatening to blow up a woman who had a previous relationship with her boyfriend.
Ailina Tsarnaeva, of North Bergen, New Jersey, made the threat against a New York City woman on the phone, police said. She later turned herself in and police charged her with aggravated harassment.
News reports said Tsarnaeva told the Harlem woman she had "people who can go over there and put a bomb on you". She will appear in court on September 30.
Her lawyer, George Gormley, said he would comment later.
Tsarnaeva has been required to report to Massachusetts probation officers since prosecutors said she failed to co-operate with a 2010 counterfeiting investigation.
Prosecutors said Tsarnaeva picked up someone who passed a fake bill at a restaurant in Boston and "lied about certain salient facts during the investigation".
At a hearing last October, Mr Gormley said Tsarnaeva was pregnant with her second child and was unlikely to flee.
Tsarnaeva once lived in Cambridge, Massachusetts, at an apartment linked to her brothers, Dzhokhar and Tamerlan Tsarnaev, the subjects of an intense manhunt in the Boston area in the days after the deadly April 2013 marathon bombing.
Records show Tsarnaeva now lives with a sister, Bella Tsarnaeva.
Dzhokhar Tsarnaev is charged with building and planting the two pressure cooker bombs that exploded near the marathon's finish line, killing three people and injuring more than 260 others. He has pleaded not guilty.
Tamerlan Tsarnaev died after a gun battle with police.
