A city-based lawyer, Mr Patrick Ongola, has on Tuesday been charged with money laundering in the Sh791 million NYS scandal.
The prosecution amended the charge sheet in the case, changing some of the dates and adding a 16th charge for three suspects.
The lawyer is facing an additional charge alongside Ms Josephine Kabura and Mr John Kago.
In the additional charge, Mr Ongola, Ms Kabura and Mr Kago are alleged to have transferred Sh90 million to K-Rep Bank account belonging to Ongola and Company Advocates.
The offence is alleged to have been committed between December 1, 2014 and May 30, 2015.
The three are charged alongside businessman Ben Gethi Wangui who is accused of arranging the purchase of a Range Rover vehicle worth Sh23 million with proceeds of crime between December 31, 2014 and April 30, 2015.
The 11 suspects were charged with money laundering charges in 2016 when prosecution lined up 50 witnesses to testify.
According to court documents, 40 witnesses have already testified in the case.
Mr Gethi’s mother and his sister, Ms Charity Wangui, are accused of allegedly arranging the purchase of a Jeep Cherokee worth Sh6.3 million.
