"The lives of two have been saved and one body was recovered," Greater Hyderabad Municipal Mayor Bonthu Ram Mohan said.
The building at Nanakramguda collapsed last night and several people were feared trapped inside the under construction structure. Rescue operations are underway since then.
"NDRF personnel along with workers of local administration are involved in the rescue operations," the Mayor said.
He said the rescue work took time as the way to the collapsed building is narrow. More machines have arrived for the operations, he said, adding some violation of rules have been found in the construction of the building.
Telangana ministers N Narsimha Reddy and P Padmarao, who supervised the operation said that the number of persons trapped inside could not be ascertained and will be known only after the debris is removed.
