The managing director of one of Tanzania’s biggest telecoms companies has appeared in court over allegations of economic crimes, including the fraudulent use of network facilities.

Hisham Hendi, an Egyptian, and other executives at Vodacom Tanzania are accused of causing the government losses of about $2.5m (£1.9m).

The firm, which is a subsidiary of South Africa’s Vodacom Group, said it was cooperating with the police investigation.

Last year prosecutors charged chief executives of a Vietnamese- owned telecoms company with similar crimes. They were released after paying a fine.

Under John Magufuli’s presidency a strict new tax regime has been introduced. Last year officials from the country’s largest gold mining company were charged with money laundering and tax evasion.
