The polling at Bastar saw Maoists open fire at seven places. Also, an Improvised Explosive Device (IED) went off in the interior, forested area.
In Sukma district, two Central Reserve Police Force (CRPF) troopers suffered gunshot wounds when Maoists attacked a polling party that was returning after the end of balloting.
Polling was delayed in at least 11 places as officials failed to reach there.
Officials failed to reach seven places in Sukma district and two places in Bijapur. In Jagdalpur district too, polling was delayed in two places as the poll authorities were not able to reach the polling centres.
There was a healthy turnout of voters in urban areas like Jagdalpur town.
However, there was comparatively much less enthusiasm in the interior, forested areas dominated by Maoists. Polling here was sluggish.
