Boston Marathon figures’ sister arrested in bomb case

The sister of the men suspected of carrying out the Boston Marathon bombings was arrested in New York Wednesday on suspicion of threatening to bomb her boyfriend’s ex, a police spokesman said.

Ailina Tsarnaeva, 24, sister of Tamerlan and Dzhokhar Tsarnaev, turned herself in to the New York City Police Department, an NYPD spokesman told the Los Angeles Times.

There, Tsarnaeva, who lives in North Bergen, N.J., was arrested on suspicion of aggravated harassment and making a phone threat, a misdemeanor, said the spokesman, Lt. John Grimpel.

The victim was an unidentified woman living in Harlem who shares a child with Tsarnaeva’s boyfriend, Grimpel said.

The arrest was first reported by The New York Post, which said that the threat was connected to a custody dispute.

Grimpel told The Times that Tsarnaeva made the threatening phone call Monday.

“Over the phone, she commented about a bomb, a bomb threat,” Grimpel said, saying that the misdemeanor charge fit what was said in the call. “If there’s a real bomb, obviously it’s different.”
