Thanks for your question. Please kindly RATE my answer when you are satisfied
I am afraid this is a scan designed to secure money from you with the intent to defraud you of the same.
An advance fee fraud is a fraud operated by individuals (scammers) whereby they request money from you on some pretext (here a fictitous bond payment) for the promise of a rewards (here the deposit promised).
This is not a legitimate arrangement and it would be best avoided and for no money to be sent under any circumstances. The matter can either be reported to the FBI and/or the British fraud police: http://www.actionfraud.police.uk/
I hope the above does not come as too great a disappointment but consider that it would be far far worse to have no deposit materialise and to have lost the money you send which I regret is an inevitability if you were to send it.
Is there anything above I can clarify for you?
How do I confirm that it is or is not a scam ?
You may consider contacting Lloyds Bank to confirm the illegitimacy for the contacts you are dealing with and the police via the above link will be able to assist.
In addition you may wish to consider contacting the financial conduct authority that regulates banks who will be able to give you further information on advance fee fraud scams
Is there anything else I can help you with?
