(Telecompaper) The Kenyan chief prosecutor has ordered a criminal investigation of six employees of mobile operator Safaricom for allegedly conspiring with election board officials to rig the 08 August presidential poll. Safaricom has dismissed the accusations as "reckless, callous and unnecessary" and warned that the allegations could endanger the lives of its members of staff and families. A letter from public prosecutions director Keriako Tobiko says a team of senior prosecutors will assist in investigating six staff members named by opposition politicians under the National Super Alliance (Nasa) for possible meddling with the election results, which were later nullified.
