The Zimbabwe Anti-Corruption Commission (ZACC) on Monday detained and charged a cabinet minister and long-time ally of President Emmerson Mnangagwa for abuse of office alleged to have cost the government $3.7 million, the second high-profile graft case this year, Eye Witness News reports.

Joram Gumbo, a minister in the presidency, was arrested on suspicion of directing a government-owned airline formed in 2017 to use a property owned by his relative as its headquarters, according to a charge sheet seen by Reuters.

Gumbo, who was transport minister at the time, is also accused of abusing his position by forcing the re-appointment of the head of a state-owned company after the official was found guilty of corruption and fired by a tribunal. ZACC said the government had suffered total losses to the tune of $3.7 million.

Gumbo was not available to comment.
