More details are emerging on what happened at last week's Department of Homeland Security raid of an apartment building in South Shore, Chicago. "Masked agents made people line up outside the building, where they asked each resident their name and country of origin before lifting their shirt to check for tattoos," a team from South Side Weekly report. "Federal agents detained nearly every resident of the 130-unit building — including children and babies — placing them in zip ties and separating them by race into vans for more than two hours." According to a DHS statement, 37 people were arrested, including four children.
