DETROIT -- Authorities say another structure that's part of Detroit's Heidelberg Project art installation has been destroyed by fire.
Project officials say the "War House" was set on fire early Thursday. The structure was next to the "House of Soul," which was burned earlier this month.
No arrests have been made but Heidelberg officials said in a statement that a security guard saw a man in dark clothing running away. A fire official said last week that arson investigators had identified a person of interest after another fire destroyed the "Penny House."
Security cameras and other measures are planned, and organizers are raising money.
Heidelberg Project creator Tyree Guyton transformed his decaying, crime-ridden neighborhood into an interactive sculpture park. His work began in 1986.
