A senior official in Governor Obado's administration was reportedly found driving a car believed to be the one used in the abduction of the late Sharon Otieno and journalist Barrack Oduor.
According to The Standard, police officers on patrol spotted the car being driven by the Migori County official who may have hired it unknowingly.
A taxi operator identified as Jack Gombe, is believed to be the driver of the black Fielder Saloon car that was used in kidnapping Sharon and the Nation journalist.
Gomber was also arrested on Sunday and arraigned in court on Monday.
He was presented before a court in Oyugis facing charges of being an accomplice in Sharon's murder.
The prosecution successfully applied to have him detained for a further ten days as the probe thickens.
The car in question is being held at a police station in Migori as a critical component in the investigations into the murder of the Rongo University student.
"We are holding the vehicle. We also arrested the driver," a detective privy to the arrests confirmed.
Police have also questioned the owner of the car to establish whether he knew that it had been hired out to the kidnappers.
The fielder is known to be operating as a taxi in Migori town but had gone missing after the incident that took place two weeks ago.
Officers say the taxi driver was either driving or in the vehicle on the day Sharon was kidnapped and later found dead near Kodera Forest in Homa Bay.
The vehicle was identified on a witness account since nation journalist Barack Oduor had claimed he escaped the captors by jumping out of the moving vehicle.
Police are also looking for a second vehicle, suspected to have been used by one of the masterminds on the day of the abduction.
The arrest brings the number of those in custody to three as sleuths pursue three other suspects who have been on the run for the last two weeks.
The Director of Criminal Investigations George Kinoti had promised to crack the case in three days but this has not materialised yet even as his team continues to place more persons and evidence into the probe.
