The family of Africa's youngest billionaire, Mohammed Dewji, who was kidnapped in Tanzania last week, has reportedly offered a reward for information leading to his rescue.
According to BBC, speaking for the first time since his abduction, Dewji's family said that they were willing to give a reward of $444 000 to anyone with information about his whereabouts.
"We [the Dewji family] want to assure anyone with the information about the whereabouts of our son to come forward and we will treat their information as secret," Dewji's uncle Azim Dewji was quoted as saying during a press conference.
Dewji, 43, was snatched by gunmen as he entered a hotel gym in Dar es Salaam on Thursday last week, AFP reported.
Police said he had no security detail with him when he was abducted.
Reports over the weekend said that at least 20 people had been arrested as police pressed a manhunt for him.
"Up until now, 20 people have been arrested," Interior Minister Kangi Lugola told reporters, without giving any detail on their identities. "Security forces are working day and night" to find him.
Officials implicated the involvement of foreigners, saying he was taken by "whites".
Dewji was chief executive of the MeTL Group which operates in some 10 countries and has interests in agriculture, insurance, transport, logistics and the food industry.
According to Forbes, he was worth $1.5 billion and ranks 17th on the list of African billionaires.
Between 2005-2015, he served as a member of parliament and in 2013, he became the first Tanzanian to grace the cover of Forbes magazine. Two years later, he was named Forbes' Africa Person of the Year.
Dewji was also the main shareholder in Tanzania's Simba FC football club.
