"Polling has been peaceful with no untoward incidents reported from any of these constituencies so far except initial reports of EVM malfunctioning from a few places. Voting began after rectifying the technical problems," an official said.
He said the polling began late - between 30 minutes and 90 minutes - in certain polling stations due to technical problems in EVMs which were rectified.

The injured polling officer, identified as Shivendra Kishore, was admitted to a hospital where he died.
The homeguard was arrested, police said.
