Furious sports clubs are taking legal action after a major sponsor failed to produce the cash. Hugh Clarke, of industrial services firm Clarke ePOS UK Ltd, is accused of welching on deals thought to amount to more than £250,000.
The conduct of the businessman, who supplies card reading systems for payments at stadia, is being investigated by the Scottish Football Association.
Legal action has been launched by Falkirk FC and Glasgow Rocks pro basketball team after Clarke failed to hand over large sums of money.
