Fire on Wednesday afternoon destroyed the southern section of De Sinco Trading’s premises on Sheriff Street, Campbellville, Georgetown.
That section is largely made of wood.
De Sinco is a major distributor of a range of consumer products.
A News-Talk Radio Guyana/ Demerara Waves Online News reporter on the scene said firefighters ran out of water.
He said the fire has since resurged and spread to the De Sinco office building.
