Returning Officer Pranjal Yadav said no untoward incident has been reported so far from any area and voting has been largely peaceful.
Snag in electronic voting machine was reported in some booths early in the morning but they were replaced immediately by the election officials.
Voters at some booths also complained about their names not being on the voter lists.
Early in the morning, Rai came along with his family members to cast his vote in Ramakant Nagar of Chetganj area, while wearing a badge of Congress election symbol ‘hand' on his kurta.
BJP and AAP protested Rai's action. Hours later, Special Election Observer Praveen Kumar sent a report to the Election Commission which asked the authorities here to file an FIR against Rai for flashing of election symbol at the booth.
