The Superintendents of Police of Guntur and Nalgonda districts -- J. Satyanarayana and Navin Gulati -- on Tuesday reviewed the security at the Nagarjunasagar dam and suggested various measures to improve the surveillance of the nation’s biggest masonry dam.

The review comes close on the heels of the twin bomb blasts at Dilsukhnagar in Hyderabad in which 16 persons were killed.

Police sources said high-level reviews on security and surveillance were usually undertaken whenever there was a major terror attack in the country.

The police officers inspected the lift, terminal, the crest gates and the tunnel. They also visited the Nagarjuna Konda and reviewed the security arrangements .Mr. Satyanarayana said security would be stepped up in the vicinity of the dam and multi-layered armed security guard system would be put in place.

Deputy Superintendent of Police, Gurazala, R. Giridhar, DSP, SPF, Ravichandra, DSP, Miryalaguda, D. Kavitha were present.
