Ten people have been charged with various election-related crimes in the Papua New Guinea capital of Port Moresby.
The Post Courier newspaper reports that Central Police Commander, Geoffery Vaki says the ten were charged with crimes that included intimidating, threatening and double-voting.
Mr Vaki says police had planned for the worst but so far they had managed to control election-related matters.
He says the guns discharged by police at Hohola, Five Mile, Six Mile, and Erima were to disperse unruly crowds and supporters.
Meanwhile Moresby North-East candidate, David Unagi's supporters have claimed there were gunshots from other candidates' camps and fights resulting in three of their men being seriously injured.
Mr Unagi's campaign manager, Newman Kaupa, also says police beat up his men when they went to check a polling booth where voting was continuing after the midday deadline.
Mr Kaupa says police used spanners and screwdrivers to beat Mr Unagi's supporters.
He says two others were speared by opposing supporters on Monday.
