“He called me on his official mobile phone and started questioning why county ODM Chairman Kennedy Ajwang’ and I were ‘plotting his downfall’. He then told me that he will shoot me wherever we meet,” Mr Ochar said.
In 2015, Mr Ouya drew his gun after a disagreement ensued at a funeral in Koru and shot in the air forcing mourners to scamper for safety.
