During a recent press conference, the city's police chief Lazaro Mambosasa went on to reveal that the kidnappers "shot into the air" before forcing Dewji into a vehicle.
The police continue their search and have arrested three men in connection to the kidnapping, the exact motivation behind the abduction unclear, though according to CNN, it is thought to likely be a "ransom" kidnapping.
Jaden Sancho admits England senior call-up was a surprise
He is snatching at chances, possibly because he is anxious about putting a foot wrong under José Mourinho. Rather they can "do a Sancho", go to another country entirely and potentially still be picked by England.
Mr Dewji is the owner and chief executive of the multibillion-dollar Mohammed Enterprises Tanzania Ltd (METL Group).
He also served as a member of parliament for the ruling Chama cha Mapunduzi party from 2005-2015.
In 2013 he became the first Tanzanian to grace the cover of Forbes magazine, and was in 2015 named Forbes Africa Person of the Year.
He said police were searching for two white men considered the main suspects. In 2016 he pledged to give half of his fortune to philanthropic causes.
Dar es Salaam regional commissioner Paul Makonda was among government officials who arrived at the scene.
