The high turnout took place despite the poll time being reduced by three hours from the normal 7 AM - 6 PM schedule to 7 AM - 3 PM.
These polling stations were spread over Katihar, Banka and Supaul constituencies, which had gone to polls with four others - Purnia, Araria, Kishanganj and Bhagalpur - on April 24, during the third phase of general elections in the state.
The Election Commission had ordered repoll at these polling stations as the EVMs developed fault and could not be replaced on time.
The EC has appointed Sanjay Bhusreddy, a Uttar Pradesh cadre IAS officer of 1989 batch as special observer for Maharajganj and Saran Lok Sabha constituencies.
Two non-bailable warrants were issued against Maharajganj RJD candidate Prabhunath Singh last week after he violated the Model Code of Conduct and allegedly threatened the District Magistrate there.
Saran constituency is witnessing a direct contest between former Bihar Chief Minister and RJD candidate Rabri Devi and BJP General Secretary Rajiv Pratap Rudy.
