Police in Zimbabwe are reportedly being left out in the ongoing investigations into a bombing incident that took place at a Zanu-PF rally in June and left at least two people dead and several others - including senior party officials - injured.According to Daily News, unnamed police sources said the investigations into the deadly bombing were still "inconclusive" despite President Emmerson Mnangagwa's claims that those responsible were now known. Mnangagwa told his supporters in August that suspects behind the bombing incident were now known and were to be dealt with after the country's election period was concluded."We now have the knowledge of who did it. We want the current (electoral) processes to pass then we will deal with that matter," the state-owned Herald newspaper quoted Mnangagwa as saying.But a top security agent told Daily News that the police were yet to identify and arrest those involved. * Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
