Some disgruntled supporters of the New Patriotic Party (NPP) in the Abuakwa North Constituency in the Eastern Region, who claim they have not been given fair treatment in the just-ended constituency elections, have invoked curses, using the powerful Osiem river deity, �Afoasua,� on the National Chairman, Mr. Peter Mac Manu, the Eastern Regional Chairman, Mr. Yaw Gyekye Amoabeng, and Constituency Chairman, Mr. Douglas Martin Asare.
