The residents said that the traders are doing the business in every street and Mohalla of the bazaar. This business is continuing with the connivance of the district administration, they added. Several fatal incidents occurred in these areas but no action has been taken. "Due to the fear of any tragic incident we are forced to shift from the street where that business is being run, said Ghulam Abbas, a resident of Raja Bazaar.
