The Karaga constituency chairman of the governing New Patriotic Party (NPP), Tahiru Zakari, has been arrested together with three others by the police on Friday.
They are suspected to be part of those causing disturbances at Karaga in the course of the week.
The rest are Baba Ali Osman, Mohammed Alhassan and Abdullai Ziblim. They were arrested on their way from Tamale to Karaga Friday evening and brought back to Tamale.
The suspects, according to the Northern Regional Police Public Relations Officer ASP Yussif Tanko, were cited by the Karaga District Chief Executive Alhassan Yabdow.
Tahiru Zakaria, the police revealed, refused to honour earlier invitation from the Regional Police Command to assist in police investigations into the disturbances.
The four are currently in police custody assisting in investigations.
