POLLING officials were among people travelling in a convoy of vehicles who were ambushed while on their way to Wabag.
The polling officials were from the Kompiam-Ambum electorate in Enga province.
The polling officials were travelling in the convoy to Wabag town yesterday morning when armed men opened fire on them at Yanda Tunda village.
Provincial police commander Supt Martin Lakari said they were driving into Wabag when supporters of another candidate blocked the road near Merimanda village and attacked them.
Lakari said the whole villagers armed with weapons attacked the passengers and also burnt their vehicle.
He said former MP Dickson Maki was taken hostage before security personnel intervened and rescued him.
Lakari said the security personnels cleared the road and brought the situation under control.
He said three men seriously injured were admitted at the Wabag general hospital.
An eyewitness who did not want to be named said the attack was related to an incident on Monday afternoon in Kompiam.
