Update 12:04 p.m.: The suspects were charged with making false statements to investigators and conspiracy to obstruct justice, a source with the U.S. Department of Homeland Security tells CNN. Two of the students are from New Bedford, Mass., while the third suspect was only identified as a U.S. citizen.
Update 11:57 a.m.: The three additional suspects are expected to face federal charges for allegedly helping to harbor and aide Dzhokhar and Tamerlan Tsarnaev while the duo attempt to evade capture, according to CBS.
Update 11:41 a.m. EDT: The three college students arrested as "suspects" in connection with the Boston bombings went to the University of Massachusetts at Dartmouth, the same school attended by Dzhokhar Tsarnaev. The three additional suspects allegedly helped him elude capture after the April 15 bombings, the Boston Globe reports. Meanwhile, the Boston Police Department tweeted that public safety was not threatened in light of Wednesday's arrests.
Three more suspects have been identified in connection with the Boston Marathon bombings, and all three individuals have been taken into custody, according to the Boston Police Department.
“Three additional suspects taken into custody in Marathon bombing case. Details to follow,” the department tweeted at 11:07 a.m.
The suspects are not believed to have played a role in making the bombs or carrying out the attacks, but instead allegedly helped brothers Dzhokhar, 19, and Tamerlan, 26, Tsarnaev elude authorities, according to John Miller of CBS.
The additional suspects were identified as college students, David Abel of the Boston Globe reported.
The revelation of three additional suspects being taken into custody comes amid reports Monday that female DNA was found on the remnants of at least one of the two bombs that exploded near the finish line of the marathon last month. But there is no information yet suggesting that development was connected to Wednesday's arrests of the three suspects.
The FBI reportedly took a DNA sample from Katherine Russell, the wife of Tamerlan Tsarnaev, earlier this week to see if her DNA matched that found on one of the bombs.
Tsarnaev died in a shoot-out with authorities April 19, a day after the FBI widely distributed photos of the then-unidentified suspects in the bombings.
His brother survived the shoot-out but was captured later in the day after hiding in a boat in the backyard of a house in the Boston suburb of Watertown, Mass. Dzhokhar Tsarnaev was arraigned on two terrorism-related charges last week.
