Former New York Giants player Clyde Hall has been sentenced to 20 years in prison for his part in several frauds, including operating an advance fee scheme.

Fake letters of credit (L/Cs) and bank guarantees were found in the one-time American football star's possession when he was arrested.

Investors duped

Hall, who is now 71 years old, posed as a representative or attorney-in-fact of two supposed business trusts.

According to an FBI statement, he duped investors by promising them various bank instruments worth hundreds of millions of dollars.

High yields

He told them that these could be used as collateral for loans or to fund trading in high yield investment programmes.

In exchange, investors were asked to pay advance fees that Hall claimed would be refundable.

L/Cs and guarantees

When Hall was arrested, officers found fake L/Cs and bank guarantees on paper bearing the logos of banks such as UBS, Citibank, J P Morgan Chase, Bank of America and Sumitomo Mitsui Banking Corporation.

Hall pleaded guilty last year to several fraud charges as well as one count of conspiracy to commit bankruptcy fraud.
