Director of Public Prosecutions Noordin Haji rejected the charges levelled against former Interior CS Fred Matiang'i.
According to the DPP, the investigating officers had provided insufficient evidence to warrant charges.
The DPP directed the DCI to close the file without any further police action.
The DCI had recommended that the former CS be charged with conspiracy to commit a felony contrary to section 393 of the Penal Code.
