Masked federal agents detained at least six workers outside the Hilltop Community Children's Center in Pittsburgh's Knoxville neighborhood on the morning of May 6, 2026. The operation occurred in a parking lot across the street from the daycare while parents were dropping off children at a nearby elementary school. Daycare staff used whistles and a toy drum to alert neighbors. Three of the detained workers, employed by a local roofing company, were subsequently released; several others remained in custody.
