NBC’s Pete Williams reports the charges are pending.
Williams also reports that the three suspects were roommates of Dzhokhar Tsarnaev and, according to the FBI, removed items from Tsarnaev’s dorm room.

The scene at Boston Federal Court:
Two of the suspects were reportedly detained for immigration violations.
More from Boston.com on two men allegedly connected to the Tsarnaev brothers who are in custody for immigration violations:
Two Kazakh men associated with the alleged Boston Marathon bombers went before a federal immigration judge this morning on allegations they violated their student visas.
The men were detained for civil immigration violations after authorities questioned them about their possible connection to Tamerlan and Dzhokhar Tsarnaev, who allegedly detonated two bombs at the Boston Marathon last month, killing three people and injuring more than 200. The brothers also allegedly murdered MIT Police Officer Sean Collier.
The two men, Dias Kadyrbayev and Azamat Tazhayakov, came to America from the Central Asian nation to study at the University of Massachusetts at Dartmouth, where Dzhokhar Tsarnaev was also enrolled.

CBS Boston reports that Azamat Tazhayakov and Dias Kadyrbayev will be charged with “conspiracy to obstruct justice and making false statements.”
As always, take these suspect IDs with a grain of salt until confirmed by authorities.
The suspects’ hearing will reportedly occur this afternoon.
A source tells the Globe that two of the suspects in custody are the Kazakh nationals detained for immigration violations.
