"The person who was transporting the money is the director of a construction company in Hela Province. Knowing there are checks at the airport, he brought the money, for him he felt the money was legal. He was transporting money for his company. He was being picked up and police felt the money was suspicious on the eve of an election."
Marape dismissed rumours the money is linked to his campaign.
"I don't need the fund for the elections. Police have kept the fund.
"I'm voting here without the help of the fund. Some think that it's a link and influenced by me, far from it.
"That fund is not needed. We're running elections on Friday. The message to my people is to vote with no conditions. And as sitting prime minister, personally, I want people to vote whether they value the office of prime minister or not."
