Police in Tanzania say kidnapped billionaire Mohammed Dewji was taken by men driving a car that had arrived from “a neighbouring country”, news agency Reuters reports.
Police Inspector General Simon Sirro declined to say which country the car came from, saying he did not want to cause a diplomatic row.
However, he said the owner and driver of the vehicle had been identified.
Mr Sirro also showed reporters a picture of the car, saying the images had been taken by CCTV cameras before the vehicle went out of view.
Mr Dewji was taken by masked gunmen in Dar es Salaam on Thursday last week. The abduction took place outside a swanky gym in the affluent Oysterbay district.
The kidnappers fired shots in the air before driving away with the billionaire, witnesses said.
His family has offered a 1bn Tanzania shilling ($440,000; £330,000) reward for information that leads to his rescue.
Mr Dewji, locally known as Mo, is credited with turning his family business from a wholesale and retail enterprise into a pan-African conglomerate.
His company, MeTL, has interests in textile manufacturing, flour milling, beverages and edible oils in at least six African states.
