BOSTON — The three additional suspects announced in the Boston Marathon bombings on Wednesday removed a backpack from suspect Dzhokhar Tsarnaev's dormitory room at a Massachusetts college after the explosions, the FBI said.
In a tweet Wednesday morning, the Boston Police Department announced that three additional suspects were in police custody, but did not provide further details. They also said there is no threat to public safety, and referred all questions to the FBI.
The FBI disclosed the information about the backpack later Wednesday afternoon. However, it is not believed that any of the three new suspects played an active role in the bombings.
Suspect Tamerlan Tsarnaev died after a gunfight with police several days later. His brother, Dzhokhar Tsarnaev, was captured and is being held in a hospital prison.
According to various officials, the three additional suspects are college roommates of Dzhokhar Tsarnaev at the University of Massachusetts-Dartmouth, and the FBI had been investigating them for more than a week.
Two of them have been held in jail for more than a week on allegations that they violated their student visas. The identity of the third suspect was not initially released.
Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line.
