DCI detectives on Monday raided an apartment in Nairobi’s Kileleshwa area and impounded fake gold and eight cars.
Some 15 suspects were arrested.
Other items were also recovered from the house which was guarded by the GSU officers.
The DCI said in a tweet that the vehicles and suspected fake gold was used to con members of the public.
Last Thursday, a businessman suspected of defrauding a Dubai royal by pretending they could sell him gold was arrested by police at Lavington Mall.
The arrest comes days after DCI boss George Kinoti via his Twitter account urged embassies and High Commissions to advise their nationals coming in for business.
