Updated: 1:52 PM EST Mar 1, 2021 A detention center in Berks County that has been the target of years of protests is no longer housing illegal immigrant families.U.S. Sen. Bob Casey (R-Pa.) said no one is living at the Berks County Residential Center near Reading.An Immigration and Customs Enforcement official told Casey the remaining families were released Friday afternoon. This is a long overdue step to deliver justice to vulnerable migrant families, including children, Casey said in a tweet. The next step is to permanently close the center so that no future family or child is forced to go through what these families have endured. The facility is owned by the county and was contracted by the federal government to house immigrant families seeking asylum in the U.S.
