Kadyrbayev and Tazhayakov, two college buddies of Tsarnaev, were jailed by immigration authorities the day after Tsarnaev's capture. They are not suspects, but are being held for violating their student visas by not regularly attending classes, Kadyrbayev?s lawyer, Robert Stahl said. They are being detained at a county jail in Boston.

(CBS/AP) BOSTON - Three men who attended college with  Boston Marathon bombing suspect Dzhokhar Tsarnaev were charged in connection with the case Wednesday.

Azamat Tazhayakov and Dias Kadyrbayev are charged with conspiring to obstruct justice. A third man, Robel Phillipos, is charged with making false statements to federal investigators.

An FBI affidavit says the three men removed bombing suspect Dzhokhar Tsarnaev's backpack from his dorm room at the University of Massachusetts at Dartmouth three days after the bombing.

The affidavit says Tazhayakov and Kadyrbayev agreed to get rid of it after concluding from news reports that Tsarnaev was one of the bombers.

Dzhokhar is in custody in a federal prison medical facility; his brother, Tamerlan, was killed in a shootout with authorities nearly two weeks ago.

Kadyrbayev and Tazhayakov have been held in jail since April 20 on allegations that they violated their student visas while attending college with Dzhokhar.

Kadyrbayev and Tazhayakov, of Kazakhstan, and Phillipos, a U.S. citizen, were reportedly arrested just outside of Boston.

The new suspects are reportedly not suspected of participating in planning the April 15 attack or putting together the two bombs that exploded in the area surrounding the finish line of the marathon.

"This more relates to what they knew and didn't divulge to authorities after the attack," CBS News correspondent Bob Orr told CBS Radio News.

The three are scheduled to appear in court Wednesday afternoon.
