The government of Papua New Guinea is being urged to send troops to Enga province, in the north, where an MP is allegedly arming himself in preparation for the June election.
The call, from Lutheran Bishop David Piso, comes as the government of Peter O'Neill announces a troop callout to the neighbouring Southern Highlands to quell law and order issues.
Bishop Piso's call also comes after Internal Security Minister John Boito this week urged MPs to give up their weapons as the election draws near.
Bishop Piso told AAP he has seen relatives of an MP in police uniform, he will not say who, but he says there has been an amassing of guns.
He says they are making homemade guns, and he has also two AK-47s.
Bishop Piso, a former military chaplain in the PNG Defence Force, has publicly urged the government to send troops to the region ahead of the election.
