The Anti-Counterfeit Agency seized 276 counterfeit Samsung phones worth Sh6.5 million during a swoop in Nairobi on Friday.
Two shopkeepers were arrested in the crackdown by ACA, working with Anti-Illicit Trade Agency Ltd, - the appointed Samsung brand protection agency.
The phones were found stocked in two electronic shops at Luthuli Avenue following a tip-off from members of the public.
"We had received particular information that there are stores trading cell phones from China with fake Samsung stickers," ACA inspector Weldon Sigei said.
"We also obtained over 1,000 duplicate mobile telephone accessories including chargers,"
Sigei asked consumers of mobile phone and other merchandise to ensure that they buy their products from authorised dealers.
"They [customers] should cultivate the culture of inquiring clear product information on quality and huge price variations from the traders. They should also demand product warranties against their purchases," he said.
He also warned traders against importation of counterfeit products into the Kenyan market, adding that the law prohibits trade in the same.
Sigei said the traders will be charged with possession of counterfeit goods for purposes of sale.
Dealers of counterfeit products are liable to jail term not exceeding five years or fine of three times the retail value of goods or both.
For second offenders or subsequent conviction, they are liable to imprisonment for a term not exceeding 15 years or a fine not less than five times the retail value of the goods or both fine and imprisonment.
"Search and seizure operations on counterfeit products run on continuous basis and as such, all perpetrators of illicit trade shall be brought to justice," he said.
