New Bedford police say that the FBI took 3 people into custody at an apartment complex in New Bedford, MA yesterday.

The two men and one woman may be classmates and possibly roomates of Dzhokhar Tsarnaev.

South Coast Today:

The FBI detained three people in connection with marathon bombing suspect Dzhokhar Tsarnaev after a raid at the Hidden Brook apartment complex Friday evening, according to New Bedford police.

Lt. Robert Richard told The Standard-Times the FBI executed a search warrant, taking into custody two college-age males and one female who are believed to be fellow students or roommates of Tsarnaev.

"At this point, they're being questioned as to ... their familiarization with suspect No. 2," Richard said around 7:30 p.m. Friday.

The names of those taken into custody were not made public.

Drug Enforcement Agency agents were seen driving out of the complex off Carriage Drive as a mass of federal, state and local police swarmed about. Neighbors flocked around the area, sharing rumors and cellphone images they had collected of the encounter.

Joe St. Pierre, a resident at the complex, said he overheard one of the men arrested being spoken to by an FBI agent.

"They said the kid got dropped off by the bomber at 4 p.m. (Thursday)," he said.

"I saw the FBI agent ... come over and interrogate him," St. Pierre said. "He was telling him 'Don't even look at me; don't be smiling. You think this is a joke?''"

Residents report seeing the younger Tsarnaev in the area as recently as Thursday. It is possible that his friends were allowing him to hide out in the apartment, although one would think that the FBI had a list of his associates and would have searched the apartment previously.

Otherwise, the three might be questioned about Tsarnaev's other associates, who they saw him with, who he mentioned that might be connected to the bombing.

The New Bedford police also think that the female in custody is Tsarnaev's girlfriend.
