The newly posted Garissa county CID commander Boniface Mwaniki has protested his posting there and opted to retire over what he called security reasons. Mwaniki wrote to the director criminal investigations department Ndegwa Muhoro to express his decision. Muhoro has accepted the move by mwaniki. Mwaniki had told his colleagues that his life was in danger following the posting in Garissa given his past work as the head of anti-terror police unit . He is among 50 officers who were transferred in latest changes in the CID to help in containing crime. Mwaniki has been a long serving head of ATPU, an elite team charged with fighting terrorism in the country. As the immediate former head of the unit, he feels he was also demoted by being posted to Garissa to head CID there given his experience and knowledge of terror matters.
