The confidential records of millions of British gamblers who bet with top bookmaker
Ladbrokes have been offered for sale to The Mail on Sunday.
The huge data theft is now at the centre of a criminal investigation after this newspaper was given the personal information of 10,000 Ladbrokes customers and offered access to its database of 4.5 million people in the UK and abroad.
The records include customers' home addresses, details of their
gambling history, customer account numbers, dates of birth, phone numbers and email addresses.
Ladbrokes last night also called in the police and began contacting customers to reassure them that their
credit card details, passwords and other financial information were safe.
The database was offered for sale by a mysterious Australian. He claimed to be a computer security expert who had worked at Ladbrokes in Britain.
During protracted negotiations via email and in one phone call, the man, who gave his name only as 'Daniel', claimed to represent a company based in Melbourne, Australia.
The company, DSS Enterprises, is run by Dinitha Subasinghe, a Sri Lankan-born IT expert.
Last night, Mr Subasinghe denied any involvement in the data theft. He designs websites and also runs a wedding planning business with his British-born girlfriend Charlene King.
Australia's companies house describes Mr Subasinghe as a 'sole trader'. His recent work has involved designing websites for estate agents in Melbourne, but he also lists Ladbrokes and the UK Ministry of Defence as clients.
He said yesterday: 'I have no access to any Ladbrokes database or any other information. I provided analytical services to them for 18 months during 2007 and 2008.'
