Express News Service KOCHI: Several heaps of unused cables are left abandoned on many areas, especially roadsides. These unclaimed cables are also causing difficulties for pedestrians and giving an ugly look to the city. Many activists have come forward demanding the corporation to take immediate action and remove them. Ranjith Tambi, an environmental activist from the city said none of the cables has any marking to denote the ownership. “If we want to ask the operator to remove them from the public places, whom should we call? None of them has names or any markings to denote the companies. It also makes the street look untidy,” he said. He added the authorities should come out with guidelines for installing cables on electric posts.
