The Boston Police Department has just announced the arrest of three additional terror suspects in the Boston Marathon bombing case.
More from the Boston Globe:
Three college students have been arrested by federal authorities in connection with the Boston Marathon bombings, a law enforcement official familar with the case said this morning.
The Boston police Web page said that three additional “suspects” had been taken into custody. It emphasized that there was no threat to public safety.
The three people were connected to Dzhokhar Tsarnaev, 19, the surviving bomb suspect, at the University of Massachusetts Dartmouth, where Tsarnaev was a student. They allegedly helped him after the bombing, a different source told the Globe.
“Additional details will be provided when they become available,” police said in a statement. No news conference was scheduled.
Up until this point, the Boston attacks carried out by brothers Tamerlan and Dzhokhar Tsarnaev have been classified as "lone wolf attacks."
President Obama expressed confidence that U.S. intelligence was functioning at a level sufficient to prevent large terrorist attacks, but warned of the difficulty agencies might have in tracking and preventing lone wolf attacks like the one in Boston earlier this month.
Yesterday is was reported that the DNA of a female was found on one of the pressure cookers used by the Tsarnaev's as a bomb.
Investigators have found female DNA on at least one of the bombs used in the Boston Marathon attacks, though they haven't determined whose DNA it is or whether that means a woman helped the two suspects carry out the attacks, according to U.S. officials briefed on the probe. The officials familiar with the case cautioned that there could be multiple explanations for why the DNA of someone other than the two bombing suspects—Tamerlan Tsarnaev and his younger brother, Dzhokhar—could have been found on remnants of the exploded devices. The genetic material could have come, for example, from a store clerk who handled materials used in the bombs or a stray hair that ended up in the bomb.
