A SCAM which involves an invitation to give bank account details in return for a share of a Nigerian windfall is now being sent by e-mail.

According to Bolton and Bury Chamber local businesses have been receiving letters and faxes on this theme for several years. But now the same dodgy message is arriving by e-mail.

Kay Gregson, the Chamber's Director of Customer Service, said today: "We have had a dozen or so complaints about these e-mails over the last couple of months.

"Anybody receiving them should simply trash them."

She said they were continuing to make representations on the issue to the Nigerian High Commission.

The latest e-mail offer -- very similar to some of those offered by post and fax in the past -- purports to be from the Nigeria National Petroleum Corporation and offers a share of 40.5 million US dollars which officials claim they need to send outside the country.
