3 new arrests made in connection with Boston Marathon bombing

Three additional arrests have been made in connection with the Boston Marathon bombing case, Boston police said Wednesday. The three who were detained were not immediately identified but were taken into custody by the FBI, police said.

Investigators have been looking into whether other people conspired with Tamerlan and Dzhokhar Tsarnaev, the brothers who allegedly detonated two bombs at the Boston Marathon on April 15.

Following the announcement of the arrests, the Boston Police Department said in a tweet: “Please be advised there is no threat to the public.”

Three people were killed and more than 260 injured when the bombs exploded near the marathon finish line.

Suspect Tamerlan Tsarnaev died after a gunfight with police several days later. His brother, Dzhokhar Tsarnaev, was captured and is hospitalized in a federal facility.

The arrests come after the CIA and departments of Justice and Homeland Security have begun a high-level internal review of whether intelligence was mishandled before the bombings, though President Obama and his top advisors said they had seen nothing to suggest counter-terrorism agencies did anything wrong.
