Fire investigators are hoping to pinpoint the cause of a fire Thursday morning at the former Imperial Knife building in Providence.
No injuries were reported.
Officials said the fire broke out on the third floor of the three-story mill building at 60 King St. The fire is considered suspicious because the building has been vacant for years and it has no utilities.
Officials said they've put out several other small fires in the building this month.
The EPA announced Wednesday that it was awarding a brownfield grant for environmental cleanup of the Imperial Knife site.
