Over 40 entrepreneurs were adversely affected by the blaze.
A senior official of the Chaguanas Business Chamber told News Power Now merchants are convinced that the incident was a case of arson.
They claim suspicious items were discovered at the site.
However, no official word on what caused the blaze has been given by the fire service.
In a News Power Now interview this afternoon, Chagauanas Mayor, Gopaul Boodan, confirmed the Corporation has been approached by the merchants for assistance.
He said the Corporation will meet soon and discuss how it can provide relief to the merchants.
