According to the documents, Arif created, maintained, and controlled over 1,500 websites that promoted the sale of the drugs while he stayed in Lahore.
The websites claimed that the drugs would cure and treat hundreds of diseases, many of which were incurable, including cerebral palsy, mental retardation, Parkinson's disease, Alzheimer's disease and emphysema.
The websites included falsified cure rates, false clinical research and fabricated testimonials, federal prosecutors alleged.
One series of websites fraudulently claimed that Arif's products had shown a 90 per cent cure rate in clinical trials.
In an effort to make customers comfortable about the products, Arif also falsely represented that the drugs were being sold by entities in Germany, Norway, Italy, Australia, New Zealand, and Denmark when in fact the drugs were all being sold and shipped from Pakistan.
