Provincial Police Commander, Acting Superintendent David Seine, says there has been a slight increase of reported cases coming in from the districts.
While some may have been unreported, he says four cases reported in the last four to six weeks are alarming.
Police in the province are currently working to apprehend all 23 people who were allegedly involved in the brutal killing of three people, accused of practicing sorcery in April.
PPC Seine says so far only three people have been arrested and charged over the killing.
He says this case was brutal, which saw the bodies of three people, accused of practicing sorcery, chopped into pieces.
The criminal cases against the three are now before the Goroka District Court, and PPC Seine says he will ensure all allegedly involved are apprehended.
“This crime is rare because it seems a whole community was involved,” he adds.
