Tanzania, May 26 -- Dar es Salaam. A Tanzanian man, Jabaldin Hamis Ijengo, has come forward alleging he played a key role in locating Osama Bin Laden.

Mr Ijengo says he provided crucial information to the US Embassy in Dar es Salaam in 2005 about Bin Laden's whereabouts in Pakistan.

The informant is now threatening to sue the US Embassy for failure to reward him for his instrumental role in disclosing the whereabouts of Osama Bin Laden, ultimately leading to his death.

"Failure to comply with this demand will regrettably leave me with no choice but to pursue legal recourse, which may involve initiating court proceedings at your own risk and expense, without further notice," warns the informant.
