The gang had a sales team of more than 100 people who pretended to be medical doctors, pharmacists or customer service assistants, and promoted the medicine at hospitals and drugstores.

Sales records from the gang showed more than 17,000 people nationwide bought various kinds of medicine from the group.

The police said the cost of one box of fake medicine was 30 to 40 yuan to produce, but the retail price went up to 1,000 yuan.

On April 14, more than 100 officers raided the gang's locations and arrested 149 suspects. Police found 10 tons of more than 120 kinds of fake medicines.
