A cleaner at the State Department Department for Correctional Services is one of 13 people under investigations by the Ethics and Anti-Corruption Commission (EACC) in connection with the embezzlement of Sh450 million.
According to sources at the anti-graft commission, five senior Ministry of Interior officials have been arrested as investigations into the graft scheme continue.
At the heart of the investigations is how the fraud suspects embezzled millions while purporting to have supplied various prisons across the country.
Other suspects include the Deputy Commissioner General of Prisons and other high-ranking officials.
