Nineteen people were arrested outside of Boston's Suffolk Detention Center Thursday after they chained themselves in protest of the Obama administration's immigration policy. Nearly 200 more marched outside the center, in growing protests as part of the #Not1More campaign

Among the 19 people arrested was 17-year-old Andres del Castillo. In a powerful statement captured on video, del Castillo explains what's at stake for mixed-status families.

Those arrested were released late Thursday evening.
