Detectives from the Anti-Counterfeit Agency (ACA) on Thursday arrested five people who were operating an illegal fuel depot in Kariokor.
The agency said the facility was disguised as a garage.
They found at least 500 litres of diesel in one of the tanks in the compound.
Five other storage tanks of fuel were also discovered.
The agency has also impounded various counterfeit high end perfumes and beauty products in the Hub shopping Mall in Karen with an estimated value of Ksh 1.5 Million.
The latest arrest comes just days after a similar number of people suspected to be running an illegal lubricant oil filling plant were arrested in Kariokor.
“We also seized packaging equipment and oil worth Sh3 million. They were also in possession of brand labels of Shell, Total Kenya and National oil,” he said.
Also, DCI detectives acting on information Tuesday evening recovered a large consignment of rolls of Garments-worth millions of shillings-in a GoDown at Mabruk House in Eastleigh.
The consignment was reported stolen on 14th March 2019 while on Transit from Mombasa Port to Changamwe Mega EPZ.
This came just hours after officers attached to the agency nabbed fake phones and phone accessories along the Luthuli Avenue in Nairobi.
Early last year, men were advised be extremely cautious when buying the Trust Studded condoms lest they land in big trouble for making partners conceive by using fake condoms produced by rent hunters.
Health experts warn that such faux products not only expose one to risks such as bursting during sex but are also made of substances that are harmful to the human body. Most of the cheap lubricating oil such underground manufacturers use produces a deadly smell, a nauseating one.
In 2013, detectives stormed a Chinese illegal production line producing millions of counterfeit brand-name condoms. These were close to perfect in appearance, imitations of top brands including Durex, Contex and Jissbon.
