Trading standards officers have seized thousands of tablets for erectile dysfunction, which they describe as 'potentially lethal'.
The prescription-only medication was found by Ealing Council workers, who smashed a major counterfeiting ring in Southall.
Suspected fakes, including handbags, watches and sunglasses, were also seized.
Councillor Ranjit Dheer, cabinet member for safety, culture and community services, said:
Samples of the suspected counterfeit goods and pills will now be taken away for testing as part an ongoing investigation.
