A government agency has arrested seven people and is in pursuit of four others linked to the processing of counterfeit cooking oil at Shimanzi in Mombasa County.

The Anti-Counterfeit Authority (ACA) said it seized documents that will help in establishing the owners of the business that is suspected to have been going on for months.

ACA and other security agents have intensified a crackdown in yards and go-downs in Mombasa's Shimanzi area where it suspects most counterfeits are re-packaged before sold.

Yesterday, the Director of Enforcement Mr Yusuf Ahmed said the operators of the yard were illegally using 13 local brands of cooking oil.
