DETROIT (AP) - Another structure that's part of Detroit's Heidelberg Project outdoor art installation has been destroyed by fire.
The blaze was reported Sunday night at what's known as "Clock House" on the city's east side. No injuries were reported.
Heidelberg Project creator Tyree Guyton transformed his decaying, crime-ridden neighborhood into an interactive sculpture park. His work began in 1986.
Including Sunday's fire, there have been at least eight fires at various structures since early May. Federal authorities are offering a $5,000 reward. The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives has been investigating the fires along with Detroit authorities.
Other structures destroyed in three separate November fires include "War House," ''Penny House" and "House of Soul." ''Obstruction of Justice House" was destroyed in October.
