A total 61.92 per cent votes were cast in the first phase of polls in 13 of the 81 assembly seats in Jharkhand amidst sporadic incidents of damage to Electronic Voting Machines.
"The percentage (of votes) could be updated later," an official with the Election Commission here said.
Palamau returning officer K N Jha said EVM machines at booth numbers 191 and 192 in Chhatarpur constituency were damaged in a minor altercation following which polling in the two booths has been cancelled.
