Hyderabad: The Hyderabad Disaster Response and Assets Monitoring and Protection (HYDRA) authorities began demolishing the ‘N Convention’ center in Madhapur on Saturday. The demolition was initiated due to allegations that the facility was constructed within the Full Tank Level (FTL) area of a lake in Madhapur. The property is reportedly owned by Tollywood celebrity Nagarjuna. Accompanied by a police contingent, HYDRA officials arrived early in the morning to commence the demolition.
