Paris – French police say they have seized 140 000 face masks destined for sale on the black market.
Officers say they caught a businessman unloading the masks from a lorry into a house in St Denis, north of Paris.
Last month, France requisitioned all stocks and production of face masks to equip health workers.
Meanwhile, in China, the authorities have confiscated 89m poor quality face masks. The country has faced criticism over poor quality exports.
Officials had inspected nearly 16 million businesses and had also seized large quantities of ineffective disinfectant, government official Gan Lin said.
And in Germany, medical wholesalers say they have almost run out of masks. From Monday it will be compulsory for people to cover their faces in shops and on public transport in the country.
The prices of masks online and in French shops had tripled before all stocks were requisitioned.
The seized masks included 5 000 high specification (FFP2) masks for use with coronavirus (COVID-19) patients. About a third were surgical masks.
The suspects included a 60-year-old man, reportedly the seller who had bought the masks for €0.50 (US$0.54; £0.44) each in the Netherlands. He was selling them for between €0.55-€0.60, Le Parisien newspaper reported.
The seller appeared to have a list of clients including company bosses, the newspaper said.
A second suspect was a 46-year-old who was allegedly about to buy some of the stock to sell on.
There have been several seizures of masks in the Paris region since the pandemic began, including 29 000 masks found in Aubervilliers and 32 000 masks sezied in Saint-Ouen, both to the north of Paris.
The country has seen 160 000 confirmed coronavirus cases and 22 600 deaths.
The huge seizure of masks there comes after several countries, including Spain, the Netherlands and Turkey, had to recall hundreds of thousands of items of poor-quality imported equipment.
In the first two months of the year, almost 9 000 new manufacturers started producing masks in China, the business data platform Tianyancha reported.
On Saturday China released new rules saying that exported protective gear had to meet international standards. (BBC)
