1:35p ET UPDATE: Catherine Herridge reports the two suspects from Kazakhstan were originally taken into custody on a violation of their student visas simply so authorities could hold them so that they could be questioned about whether they took any action after the FBI posted photos of Dzhokhar and Tamerlan Tsarnaev.  Authorities tell Fox News that the men will be charged with obstruction of justice. The source also says that at least one of the men was asked by Dzhokhar to dispose of a package.

1:31p ET UPDATE: David Lee Miller reported from outside the court house that two of the suspects have been identified as Azamat Tazhayakov and Dias Kadyrbayev. Officials say the third suspect, the American, was arrested for doing “bad things” to hinder the investigation. The two named suspects are pictured in the photo below with Dzhohkar Tsarnaev.

12:15p ET, UPDATE: Sources tell Fox News that two of those arrested are from Kazakhstan and face obstruction-related charges. There were also issues with their student visas. Authorities suspect the men tried to dispose of something at the request of Dzhokhar Tsarnaev after he and his brother, Tamerlan, went on the run. No information at this time on the third suspect.

11:36a ET, UPDATE: One source familiar with the arrests tells Fox News that the charges against these suspects have to do with assistance or cover they may have given to the Tsarnaev brothers.
