Several employees of a pharmaceutical company have been arrested in Indonesia for allegedly washing and reselling used Covid-19 nasal swab test kits.
According to BBC, up to 9,000 passengers at an airport in Medan may have been tested with the reused swab sticks, say police.
State-owned company Kimia Farma is now reportedly facing a potential lawsuit launched on behalf of the travellers.
Covid-19 nasal swab testing has become routine in many countries hit by the global pandemic.
Police said they believed the scam had been happening since last December at Kualanamu airport in Medan, North Sumatra.
Passengers are required to have a negative test if they want to fly, and the airport offers the option of getting the swabs done on-site. Airport authorities had used antigen rapid test kits supplied by Kimia Farma.
When he was swabbed and received a positive test result, other officers swooped in and raided the test site, where they found a used test kit that had been recycled.
Last week, five Kimia Farma employees including the company’s Medan manager were arrested. The suspects are accused of breaking health and consumer laws by washing nasal swab sticks and repackaging them for sale.
Local media said authorities have compiled reports from 23 witnesses, and are investigating whether the profit from the scam estimated to be around 1.8bn rupiahs (£89,700; $124,800) was used to fund the construction of a lavish house for one of the suspects.
Kimia Farma, which is headquartered in the capital Jakarta, has since fired the staff involved and promised to tighten internal controls.
Indonesia has seen one of the worst Covid outbreaks in Asia, and overall has recorded about 1.7m positive cases and more than 46,000 deaths linked to the pandemic.
