Interior Cabinet Secretary on Tuesday visited the National Transport and Safety Authority offices overproduction of fake documents.
The Cabinet Secretary accompanied by top ministry officials read a riot act and directed them to immediately put their house in order.
He held an hour-long meeting with the board members before leaving, saying he will be back in two weeks.
His visit came as officials said a section of staff kept off office as police went on with investigations into the alleged production of fake documents.
Detectives visited the NTSA offices on Monday and Tuesday for investigations but did not find some staff.
The officers were targeting staff working in the IT section and some managers to understand the process an applicant goes through in getting documents.
Banks also raised concern with the authorities over the said fraud, which prompted the Directorate of Criminal Investigations to post detectives at NTSA.
The latest move came after over 450 genuine motor vehicle logbooks were recovered at a cyber cafe in Nairobi on December 17.
Police said some officials at NTSA might be part of an organized criminal gang that is behind the organization hence putting the lives of many unsuspecting motorists at risk.
