All these extremely naive people who invested money into the scheme, invested into SUFC (1988) LTD, a company solely owned by David Hilton, a sole trader and Director, they did not invest in any company associated with Scunthorpe United Football Club.
They have no claim legally against the club. The claim is against the owner of the company they invested in, that company is still trading and a simple google search will point them in the direction.
