Police from six provinces, including Fujian, Anhui and Zhejiang, arrested 43 suspects in a major case of fake brand-name sanitary napkins, the Ministry of Public Security said on May 14.

The amount of money involved was as much as 150 million yuan ($24.4 million).

Since February, Quanzhou police in East China's Fujian province have received many reports from women who said they didn't feel well after using the products, the ministry's economic crimes investigation bureau said on Tuesday.

Police later discovered a major criminal network involved in the manufacture and sales of counterfeit sanitary napkins.

In March, police smashed 43 dens used for manufacturing, storing and packing the fake goods, and they closed 20 production lines, the ministry said.

Besides Fujian, the provinces involved were Anhui, Zhejiang, Hunan, Sichuan and Hubei.

Meanwhile, police seized 19.6 million sanitary napkins that were counterfeits of some well-known brands, and seized more than 100 tons of counterfeit raw materials.
