DR.JOHN KUKU AUDITING AND ACCOUNTING UNIT FOREIGN REMITTANCE DEPT CREDIT BANK BENIN COTONOU-BENIN REPUBLIC WEST AFRICA.
My dear,
I am Dr.John Kuku, the director in charge of auditing and accounting se= ction of Credit Bank Benin republic in West Africa with due respect and= regard. I have decided to contact you on a business transaction that w= ill be very beneficial to both of us at the end of the transaction.
During our investigation and auditing in this bank, my department came = across a very huge sum of money belonging to a deceased person who died= on 30th January 2000 on Kenya Airways with aircraft Airbus 310-304 at = location Abidjan, Ivory Coast, with registration number 5Y-BEN while tr= aveling with his entire family, his wife, two children and a maid on a = festive visit to Abidjan and since his untimely death the funds has bee= n dormant in his account with this Bank without any claim of the fund i= n our custody either from his family or relation before our discovery t= o this development.
Although personally, I kept this information secret within myself and p= artners to enable the whole plans and idea be Profitable and successful= during the time of execution. The said amount was USD\16.4M (16.4)Sixt= een Million Four Hundred Thousand united states dollars).
As it may interest you to know, I got your impressive information throu= gh my very good friend who works in the computer department of the fede= ral ministry of information and tourism here in Cotonou-Benin Republic = during my search for a foreign partner to execute this transaction. She= is the one who recommended your person to me to be viable and capable = to champion a business of such magnitude without any problem.=20
Meanwhile the whole arrangement to put claim over this fund as the bona= fide next of kin to the deceased and get the required approval and tra= nsfer this money to a foreign account has been put in place, all direct= ives and needed information will be relayed to you as soon as you indic= ate your interest and willingness to assist us and also benefit yoursel= f to this great business opportunity.
In fact i could have done this deal alone but because of my position in= this country as a civil servant, we are not allowed to operate a forei= gn account and would eventually raise an eye brow on my side during the= time of transfer because i work in this bank.=20 This is the actual reason why it will require a second party or fellow = who will forward claims as the next of kin to the Bank and also present= a foreign account where he will need the money to be re-transferred in= to on his request as it may be after due verification and clarification= by the correspondent branch of the bank where the whole money will be = remitted from to your own designated bank account.
May i at this point emphasize that this transaction is 100% risk free a= s i have made all arrangements for a successful transaction as an insid= er of the bank before contacting you.
On a smooth conclusion of this transaction, you will be entitled to 30%= of the total sum as gratification, while 10% will be set aside to take= care of any expenses that may arise during the time of transfer like t= elephone bills, fax and our travel tickets to come over to your country= for the sharing of the fund while 60% will be for me and my partners. Please you have been advised to keep this a top secret as we are still = in service and intend to retire from service after we conclude this dea= l with you.
I will be monitoring the whole situation here in this bank until you co= nfirm the money in your account and ask us to come down to your country= for subsequent sharing of the fund according to percentages previously= indicated and further investment either in your country or any country= you will advice us to invest in.
All other necessary information will be sent to you on your acceptance = to champion this transaction with me.=20
I suggest you get back to me as soon as possible stating your wish in t= his deal. Yours Faithfully,
Dr.John Kuku ALTERNATIVE EMAIL: dr_johnkuku@zwallet.com
