The Army and the FBI Sunday night took over Detroit to insure protection of her vital defense industry.
Four truckloads of Selfridge Field troops arrived in the city at a late hour to set up guard at the Ambassador Bridge and the Detroit-Windsor Tunnel. Similar precautions were planned for the Michigan Central Railroad Tunnel under the river and vital carferries.
