(Bloomberg) -- A Tanzanian billionaire industrialist who was abducted about nine days ago has returned home unharmed, his charitable foundation said.

Mohammed Dewji, listed by Forbes as Africa’s youngest billionaire with a net worth of $1.5 billion, thanked Tanzanian authorities for his safe return, the Mo Dewji Foundation said early Saturday on Twitter. It gave no further details on his kidnapping or release.

The Daily News, a local newspaper, said his family confirmed his release.

The 43-year-old was seized by unidentified people in the Tanzanian commercial hub of Dar es Salaam on Oct. 11. Dewji owns MeTL Group, a conglomerate operating in several African countries and contributing about 3.5 percent to Tanzania’s gross domestic product, according to its website.
