Police in the Papua New Guinea province of Madang are ruling out a common motive in two attacks on judges that have occurred in the past few weeks.
The acting provincial police commander says Judge David Cannings was travelling home from the Madang Country Club when he was held up by six young men with a gun and bush knife and robbed of his vehicle.
Kiweri Kesambi says police are following leads on the case along with those on another attack on a senior magistrate and his family in their home.
He says police don't believe the attacks are linked with each other or with work the judges have been doing.
"It's just coincidence that they...I mean the judge just happened to be in the place where he was attacked. I have arranged for a policeman on the ground to keep a constant patrol along the east west area and that area where he was attacked, we are monitoring that area as well, as well as the senior provincial magistrate."
