"During repair and maintenance work, the pinnacle was found to be weak and showed clear signs of ageing. It was, therefore, brought down for repairs on Monday," an Archaeological Survey of India (ASI) official said.
The iron rod of the pinnacle was rusty and weak and needed to be replaced, he said, adding that fresh mortar has to be filled to provide stability to the surface "which remains exposed to elements".
Social media was abuzz yesterday with talk that the pinnacle of one of the four minarets of the 17th century monument -- a UNESCO World Heritage Site -- had "fallen off" during repair work and was "in pieces".
Meanwhile, Conservation Assistant Ram Ratan today said that work has begun to restore the damaged pinnacle. Efforts would be made to re-install it within a week, another official said.
