A son of Mozambique’s former President Armando Guebuza has been detained over a $2bn (£1.5bn) government debt scandal.

Ndambi Guebuza, the eldest son of the former leader who stepped down in 2015, was detained in Maputo, the capital, on Saturday, according to local media.

He was the ninth person to be detained in this case in less than four days.

Others include Mr Guebuza’s then-head of security and intelligence, Gregorio Leao, then-head of economic intelligence, Antonio de Rosario, and his former private secretary Ines Moiane.

It is alleged that the government, while Mr Guebuza was in office, had taken out loans worth $2bn in order to fund various projects taken on by state-owned companies in the fishing and maritime security industries.

However, the transaction was allegedly hidden from parliament and international donors.

President Filipe Nyusi came to office 18 months ago after the debt had been acquired. He insists that his team knew nothing about it.
