Federal officials have fanned out into area neighborhoods in search of people who are suspected of being in the U.S. illegally.
The change in enforcement tactics comes as Prince William County ended its relationship with federal Immigrations and Customs authorities in June. Under the old 297(g) agreement that had been in place since 2007, customs officials were notified when a suspect with a federal detainer to their name was released from the Prince William County Adult Detention Center in Manassas.
