Investigators say a five-alarm fire in Baltimore's adult entertainment district was not accidental, though they haven't yet determined if it was arson.
The Bureau of Alcohol, Tobacco, Firearms and Explosives says the fire has been classified as "incendiary," meaning it was set by someone. But officials say they don't know what the intent of that person was, and no suspects have been identified.
The fire on Dec. 6 destroyed a building that was home to two strip bars and an adult bookstore. It formed a cloud of black smoke over downtown, and several nearby buildings were also damaged. No one was injured.
Investigators are offering a $5,000 reward for information that leads to a resolution of the case.
