Two men and a woman linked to a housing complex where one of the Boston Marathon bombers may have stayed were being questioned Friday night in New Bedford, Mass., police said.

The subjects were not under arrest, New Bedford Police Dept. Lt. Robert Richard told Fox News.

They were being questioned after police executed a federal search warrant at the Rockdale West House Complex, an apartment often used for rentals to students who attend the University of Massachusetts at Dartmouth.

Boston Marathon bombing suspect Dzhokhar Tsarnaev is a registered student at the university, and is believed to have resided at the apartment complex at one point in the recent past. Sources told Fox News he was seen at or near the complex after Monday's attack, which killed three and injured 176.
