Rescue operation is now going on.
All the victims in the tragedy are workers who lived at the cellar of the building.
Nine of those killed hailed from Vijayanagaram district and one from Srikakulam district in Andhra Pradesh. "After removing the debris from a side and the middle, most of the bodies were visible and retrievable", said an NDRF official.
From being a small time arrack seller to becoming a real estate dealer, it was not a very long journey for Satyanarayana Singh, the owner of the collapsed building at Nanakramguda.
Cyberabad police apprehended builder Narayan Singh alias Sattu Singh who illegally constructed 7 storied building at Nanakramguda which collapsed on Thursday. Rescue workers pulled out 12 people from the rubble and shifted them to a nearby hospital.
Telangana ministers N Narsimha Reddy, P Padmarao and K T Rama Rao were among those who supervised the operation.
NDRF personnel along with members of the local administration were rescuing the victims at the site of the Hyderabad building collapse in Nanakramguda.
Telangana Home minister N Narshimha Reddy said different figures were being given on the number of persons trapped under the debris.
"Unless the slabs are removed, we cannot say responsibly".
He is locally known as Gudumba Singh, and also had been arrested several times for illegal arrack trade, but since then, his family now holds substantial land and is involved in many real estate deals.
"Some say six persons have died and some say seven died".
The immediate priority right now is to remove the debris and ascertaining how many were trapped, he said.
Expressing anguish on the collapse of the multi-storey building, Chief Minister K Chandrashekar Rao directed ministers from the city to take care of the rescue and relief operation.
The government has suspended Sherlingampally Deputy Commissioner of Greater Hyderabad Municipal Corp (GHMC) Manohar and an Assistant town planning officer Krishna Mohan over lapses.
