Dear Friend,
I am the Manager of the Accounts and Audit Section at the African Development Bank in Abuya. In my department we discovered an abandoned sum of US$10m US dollars(Ten million US dollars) in an account that belongs to one of our foreign customers who died in a plane crash. We have been expecting his next of kin or relation to the deceased. I now decided to make this business proposal to you and release the money to you as the next of kin since nobody is coming for it. I agree that 40% ot this money will be for you as respect to the provision of a foreign account, and 60% will be for me. To enable the immediate transfer of this fund to you, you must apply first to the bank as relation of next of kin of the deceased indicating your bank account number, your private telephone and fax number. Yo should contact me immediately as soon as you receive this letter
Mr. Allasane Akeem
