Zimbabwe's health minister Obadiah Moyo was arrested on Friday for alleged corruption related to the supply of medical materials to combat the coronavirus pandemic, the anti-graft agency said.

The government did not immediately comment on the arrest, which came a day after the country's main opposition condemned alleged state corruption following suspicions over a $2-million-dollar payment to a medical company contracted to provide anti-coronavirus equipment.

Harare has come under fire for granting two-month-old company Drax Consult SAGL a contract to supply $20 million worth of drugs, personal protective equipment and Covid-19 test kits.

In March, authorities in Hungary - where Drax Consult SAGL is registered - flagged a suspicious $2 million deposit into the company's accounts, drawing anger from the opposition Movement for Democratic Change.

Government last week ordered the cancellation of all contracts for the supply of medicines and sundries by Drax, according to the state-run Herald newspaper.
