The driver was probed at the CID headquarters together with four other suspects arrested in connection with the death of the ambassador who was aged 57 at the time of her death.
He alleged that there were leadership wrangles at the embassy.
This happened as two senior government officials from Venezuela arrived in Nairobi to push for full investigations and arrests of the culprits.
The ambassador is suspected to have been murdered on Thursday night after a party in her house where the driver claims some staff members had suspiciously been taking pictures in the residential area.
Presently, there are nine suspects in police custody including the embassy’s First Secretary whose diplomatic immunity was waived.
The suspects were separately arrested in Kayole, Mwiki, Muthaiga and Dandora.
Nairobi Area police boss Anthony Kibuchi said investigations were progressing well and they expected to charge some of the suspects by Tuesday depending on the outcome of the investigations.
“They are writing more statements before they appear in court. We are making good progress in this murder incident,” he said.
The Venezuelan officials were said to have visited the scene of the murder on Sunday before viewing the body that is lying at the Lee Funeral Home.
A team led by Nairobi CID boss Nicholas Kamwende were still recording statements from the suspects and they expect to press charges of murder once through with their investigations.
“Definitely we will take some people to court. It is a matter of time,” Kamwende said..
Police said the deceased who had been in Nairobi for just about two weeks before her death was yet to get police escort and her residence was not guarded by police.
It is said that she had been residing at a hotel and had only moved to the official residence in Runda two days before she was killed.
Her body was discovered on Friday morning with signs that she had been strangled.
