The investigation into the Boston Marathon bombing seeped into New Bedford, Mass. on Friday evening with the questioning of several people who knew suspect Dzhokhar Tsarnaev.

After local and state police and FBI agents allegedly searched Dzhokhar Tsarnaev's UMass Dartmouth dorm room, authorities swarmed to the Rockdale West apartment complex in New Bedford's West End. Three people, allegedly friends of the Tsarnaev, were taken away with police for questioning.

Joe St. Pierre lives several doors down from the apartment at 69 Carriage Drive, and tells WBSM News he heard an FBI agent yelling at one of the people being taken into custody.

New Bedford Police say the three people in custody are being questioned by the FBI.

One neighbor says he had a friendly relationship with Tsarnaev, and the three who were questioned share the same cell phone bill with the bombing suspect.

Police say Tsarnaev spent a substantial amount of time at the Carriage Drive apartment.
