Authorities say a person trying to salvage scrap metal from an underground tunnel at Detroit's Packard complex hit a natural gas line, sparking a fire at the former car plant.
The Detroit News and Detroit Free Press report crews with DTE Energy Co. shut off the flow of gas after the Thursday rupture. Fire department Cmdr. Thomas Burt says crews searched but weren't able to find the person believed to have sparked the fire.
The utility says it's investigating.
Also Thursday, officials said Peruvian developer Fernando Palazuelo made his final payment toward the $405,000 purchase price for the complex, a symbol of Detroit's decline. Palazuelo has said he has a roughly $350 million plan to use the site for residential, retail, offices, light industry, recreation and art.
