Two men from a housing complex connected with Boston marathon bombing suspect Dzhokhar Tsarnaev have been arrested, the police said.

The Associated Press reported Friday that two males and a female were taken into custody for questioning at an off-campus housing complex at the University of Massachusetts Dartmouth. Tsarnaev was a student at the school, and police say he may have lived at or been affiliated with that building, according to the Associated Press.

Officer John Indio of the New Bedford police told MassLive.com on Sunday that the three individuals were released. However, law enforcement then went back and arrested the two males.

Indio said he believes the men were friends with Tsarnaev and classmates of his at UMass Dartmouth. A UMass Dartmouth official confirmed that the men had been students in the past. He was unable to provide information about why they left the university or their current status.

Indio said the New Bedford police did not have any information about the nature of the charges, the names of the two men or what connection, if any, they had to the Boston Marathon bombing case.

The Federal Bureau of Investigation referred calls to U.S. Immigration and Customs Enforcement, indicating that the charges may have been immigration-related. A spokesman from ICE did not immediately return a call. The two bombing suspects, Tsarnaev and his brother Tamerlan Tsarnaev, were Chechen immigrants.

The news site South Coast Today, the website of the New Bedford Standard-Times, reported that the two men were arrested Saturday afternoon at the Hidden Brook apartment complex in New Bedford by agents wearing FBI and Department of Homeland Security jackets.

UMass Dartmouth reopened on Sunday. The campus had been evacuated on Friday and remained closed on Saturday.

Dzhokhar Tsarnaev was arrested Friday night after he and his brother allegedly killed an MIT police officer. Tamerlan Tsarnaev was killed in a firefight early Friday morning. A day-long manhunt for Dzhokhar Tsarnaev put much of the Boston area under lockdown.
