Three new Boston suspects: Dias Kadyrbayev, Azamat Tazhayakov and unnamed American student

Three new suspects were arrested in connection to the Boston Marathon bombing and they are thought to be Dzhokhar Tsarnaev’s roommates, Kazachs  Dias Kadyrbayev and Azamat Tazhayakov and an unamed American, who helped him cover his tracks after the fatal blasts.

The Boston Police Department were the first ones to report the arrest over their Twitter feed, and The Boston Globe claimed that the three people in custody were college students and the roommates of the younger bomber, Dzhokhar Tsarnaev.

Federal sources told The Washington Post that the three students disposed of undisclosed material in a landfill on behalf of their 19-year-old Chechen friend Dzhokhar Tsarnaev following the bombing.

The clue fits as police were seen searching a landfill in nearby New Bedford, Massachusetts last week during their search for evidence in the case.

Two of the suspects, identified as Dias Kadyrbayev and Azamat Tazhayakov, were already in police custody in regards to an immigration issue that investigators discovered after questioning them over their license plates that read “TERRORISTA#1”. Those two friends are Kazakh citizens and the third is thought to be an American national.

The three are charged with making false statements and conspiracy to obstruct justice, which implies that they were not involved in actually carrying out the attack but rather helping the suspect evade police after the fatal blasts.

The claims were reiterated by NBC’s Pete Williams, who said that Dzhokhar Tsarnaev’s roommates were arrested Wednesday and charged with giving false information to police.

The three were all students at UMass Dartmouth- where Dzhokhar Tsarnaev was enrolled- and that they helped him after the April 15 bombings.

This is not the first time that the bomber’s roommates have come under investigation, as they prompted alarm bells after it was revealed that they were driving a BMW with license plates that read “TERRORISTA#1”.

Dias Kadyrbayev and Azamat Tazhayakov remained in custody over immigration issues as they are Kazakh nationals whose academic visas had expired.

CNN has since identified Dias Kadyrbayev and Azamat Tazhayakov as two of the three friends that were arrested today.

The third person in custody on Wednesday is believed to be an American citizen who will be charged with making a false statement, according to CBS.

Attorney Robert Stahl told CBS that they were drawn to Dzhokhar Tsarnaev because he also spoke Russian.

The attorney confirmed they now face separate federal charges and have an afternoon court appearance related to the bombing case.

CBS reports that the men will be charged conspiracy to obstruct justice and making false statements.

ABC affiliate WCVB reports, citing a lawyer who was briefed on the case early Wednesday, that the three suspects disposed “of a backpack full of fireworks that was in Dzhokhar Tsarnaev’s dorm room, done at the request of Tsarnaev sometime after the bombing.”

CBS reports that the suspects were arrested for “harboring or aiding the suspects after the fact” and that they are in the custody of the FBI.

“At this point, we’re not really in a position to make any comment,” FBI spokesman Alison Mahan told Talking Points Memo.

The Boston police followed up their initial tweet by confirming that there is no threat to public safety.

The news of the arrests comes one day after the elder suspect Tamerlan Tsarnaev’s wife Katherine Russell was interviewed by investigators after they spent hours searching her home.
