Police in Kerema intercepted four suspects paddling a dugout canoe on the Murua River after villagers grew suspicious, and the men led officers to a campsite at Lorope holding eleven bags with 84.5 kilograms of marijuana.[1] It was the biggest marijuana haul recorded in the country at the time, and the National Drug and Vice Squad would give no street value for fear of encouraging more smuggling.[1][2]

The four were part of a group of 13 that had smuggled the drug from Goroka in the Eastern Highlands via Morobe; the other nine fled into the bush as Kerema police approached the campsite.[1] The four were taken to Kerema police station and charged, then held at the Boroko police cells to face the Boroko District Court in Port Moresby.[1] Officers believed the packs were bound for the overseas market or for gun trading, and found phone messages they linked to bigger operators.[1]
