Dias Kadyrbayev and Azamat Tazhayakov, nationals of Kazakhstan, who were residing in New Bedford on student visas, were charged Thursday with conspiracy to obstruct justice and obstructing justice with the intent to impede the bombing investigation.
Kadyrbayev and Tazhayakov attended the University of Massachusetts Dartmouth with Tsarnaev. They were originally charged with conspiring to obstruct justice on May 1 after seeing Tsarnaev's photo on television as a suspect in the bombings. Their lawyers said the men had no role in the bombings.
If convicted, Kadyrbayev and Tazhayakov face up to 20 years in prison on the obstruction of justice count and up to five years in prison on the conspiracy count, each to be followed by up to three years of supervised release and a $250,000 fine.
The two will be arraigned Aug. 13 at 2 p.m. in federal court. They face the possibility of being deported.
