Edson Chidziya, the former head of Zimbabwe’s National Parks, has been charged with criminal abuse of office over a missing consignment of rhino horns.
Mr Chidziya is accused of mismanagement that led to a security breach and the theft from a strongroom of rhino horns worth $3m (£2.3m).
They disappeared between 2012 and 2015 and were never recovered.
Mr Chidziya was released on bail of $200 along with three other parks staff.
Zimbabwe has a massive stockpile of high-value rhino horns and elephant ivory which it cannot sell because of a global trade ban.
