The former Leeds United chief David Haigh has been accused of financial mismanagement amounting to $5 million by his previous employer Gulf Finance House Capital, a report said.

Documents from the Dubai International Financial Centre have revealed the extent of the allegations against Haigh, who denies all wrongdoing, said The Guardian report.

Haigh is being held in a Dubai police station for the 18 days.

GFHC, a subsidiary of Gulf Finance House, accuses Haigh of fraud and embezzlement, with detailed documents alleging he fabricated at least 55 invoices to secure payments to five different bank accounts, two in Dubai and three in the UK, said the report.

GFHC claims the financial invoices relate to four different companies whose representatives have presented affidavits to the Dubai court denying that they were aware of their existence or the relative bank accounts.

Haigh has not been charged with any criminal offence, it said.
