The six-alarm fire raged for hours and left four fighters with minor injuries.
The six-alarm fire that burned down an Alexandria warehouse on Labor Day appears to have been intentionally set, and city officials have identified a person of interest.
Officials with the Alexandria Fire Department say they have ruled out all accidental causes for the fire after conducting an investigation with the Bureau of Alcohol, Tabacco, Firearms and Explosives. The case is now being handled by the Commonwealth's Attorney.
No one was inside the warehouse on South Pickett Street when the fire broke out, but four firefighters were taken to area hospitals with minor injuries while battling the six alarm blaze on September 2.
Officials estimate the fire caused about $6 million in damages.
