The voting in the bypoll to the Ellenabad Assembly constituency went off peacefully on Saturday, registering an average voter turnout of 80 %, which sealed the fate of 19 candidates, officials said.
The polling remained peaceful, they added.
The voting percentage might change as the polling data was still being compiled, the officials said.
The Ellenabad seat had recorded a 83.6 % voter turnout in the 2019 Assembly polls.
The polling began at 7 a.m. and continued till 6 p.m., the officials said.
The counting of votes will be taken up on November 2.
The bypoll was necessitated by Indian National Lok Dal (INLD) leader Abhay Singh Chautala's resignation as the MLA from the seat in January in protest against the Centre's new farm laws.
Nineteen candidates, including Chautala, Pawan Beniwal of the Congress and BJP-JJP nominee Gobind Kanda, were in the fray in Ellenabad, which has more than 1.86 lakh voters.
A total of 211 polling booths were set up and 121 of those were categorised as "sensitive and hyper-sensitive", the officials said.
Tight security arrangements were made for the bypoll as 34 companies of paramilitary forces and police personnel from different districts were deployed.
Gobind Kanda, the brother of Haryana Lokhit Party chief and legislator Gopal Kanda, joined the Bharatiya Janata Party (BJP) recently.
Beniwal, who had unsuccessfully contested the previous Assembly polls against Chautala, recently switched over from the BJP to the Congress.
Chautala, Beniwal and Kanda were locked in a triangular contest in the Ellenabad bypoll.
Beniwal cast his vote in Darba Kalan village in the morning.
