BOSTON (AP) — Several advocacy groups have sued the Boston police and school departments to find how much information they share with federal immigration officials.

Lawyers for Civil Rights, the Center for Law and Education, and Multicultural Education, Training, and Advocacy filed suit in Suffolk Superior Court on Thursday for details on how police and schools share student information with U.S. Immigration and Customs Enforcement.

The Boston Globe previously reported that the city has shared information about Boston Public School students involved in fights, disturbances or vandalism more than 100 times between 2014 and 2018 with the Boston Regional Intelligence Center, commonly known as BRIC. The agency includes an agent from the Department of Homeland Security.

David Carabin, assistant chief of the BRIC, said the unit doesn’t work with federal authorities on immigration proceedings.

“ICE does not have access to a drop of data that sits within the Boston Police Department,” Carabin said under questioning from city councilors during a hearing on grant funding on Thursday.

The school system has said it no longer shares such reports.
