An investment fund manager who spent millions of pounds of investors' money after using Google to forge author Terry Pratchett's signature has been jailed for seven years.

Benjamin Wilson, 35, duped "several hundred" investors including close friends and colleagues into investing nearly £22 million into SureInvestment, London's Southwark Crown Court heard.

He used the cash to pay for a multimillion-pound new home as well as buying racehorses, a luxury sports car and gambling in Las Vegas.

Wilson doctored business statements to hide his fraudulent activity by copying the author's signature.

Judge Michael Grieve said Wilson had carried out an "utterly shameless confidence fraud".
