Boston’s immigrant communities are responding with anger and fear to the recent arrests of some 50 people across the state by federal agents this week. Immigration and Customs Enforcement — or ICE — targeted Massachusetts as part of a nation-wide crack-down on people in the country illegally who had also committed crimes. But immigrant advocates in Boston say the raids are sweeping up the innocent and leaving neighborhoods terrified.

Boston Public School officials say they are expecting many young Puerto Ricans to arrive in the district in the wake of Hurricane Maria. On Thursday, the district and its partners got together to anticipate the needs of those students and their families, and brainstorm how they could meet them.

Normally, Sonia Gomez-Banrey runs an early-education program for Boston Public Schools. But today, she’s thinking about the destruction in Puerto Rico.

Seventy-eight-year-old Alonso Mercado and his wife emerged from the gates at Logan Airport on Wednesday evening to see their children and grandchildren. They came from Puerto Rico to take refuge with family in the United States.

Being in the Boston, Mercado says, is like paradise.

“Like in heaven,” he says.

Mercado says his home is ruined, and he plans to stay on the mainland until Puerto Rico returns to normal.

“We didn’t have no light and no water,” Mercado says. “No electricity in the house, not in the house, in the whole Puerto Rico.”

Berkshire Bank says its planned move to Boston will have little impact on workers at its current headquarters in Pittsfield.

The move to Boston is largely driven by Berkshire's planned acquisition of Commerce Bank, which has 19 branches in central and eastern Massachusetts.

Sean Gray, chief operating officer of Berkshire Bank, said there will be no job losses in Pittsfield and the city will remain an operational center for the bank.

He said moving its headquarters to Boston will get executives closer to regulators, lawmakers and the financial hub of the region.
