The brutal murder of a celebrated Papua New Guinea businessman highlights how shantytown communities across the country are fuelling violent crimes. Six young men have been arrested in connection with the killing of Cyprus-born building tycoon Sir George Constantinou, 75, who died during a botched car-jacking on Tuesday night near one of his timber yards in a notorious part of Port Moresby. Authorities threatened to destroy shanty homes in the nearby Tete settlement if the culprits were not handed over.
