The polling passed off peacefully and no complaints were received, according to Medak District Collector and Election Officer Ronald Ross.
The voting took place from 7 AM to 5 PM at 286 polling stations.
The 81 per cent turn out of voters was 2 per cent higher than the poll percentage reported during 2014 Assembly election.
Live web casting and videography was also conducted in the bypoll, necessitated by the death of sitting Congress MLA Patlolla Krishna Reddy, popularly known as Kishta Reddy.
