"The IG has instructed police commanders of jurisdictions where by-elections were carried out to arraign and charge the four leaders who were arrested yesterday [Thursday]," the statement by Police Spokesperson Charles Owino read in part.
"The IG has equally instructed the Firearm Licensing Board to suspend firearm licenses held by the said political leaders who misused their firearms. The affected individuals are hereby instructed to surrender the firearms to DCI headquarters with immediate effect for ballistic examination," the IG directed.
