A convicted rapist is suspected of using a fake ticket to claim a £2.5 million National Lottery jackpot.
A man, named in reports as Edward Putman, 51,is believed to have claimed the prize with a "deliberately damaged ticket" in 2009.
Putman was jailed in 1993 for rape.
On Friday, it emerged that lottery operator Camelot has been fined £3 million by the gambling watchdog after an allegation of fraud.
The Gambling Commission, did not confirm how much Camelot had paid out, said the penalty included the money good causes would have received had the prize claim not been paid.
Hertfordshire Police has confirmed a 50-year-old from Kings Langley was arrested in October last year on suspicion of fraud by false representation.
He was later released without charge.
A £2,525,485 jackpot from a draw on March 11 2009, went unclaimed until shortly before the September 7 deadline the same year for it to be given to good causes, according to news reports at the time.
The arrest followed information from Camelot following the death of a security official at the company who was said to have been part of an alleged plot, The Times (£) reported.
Shadow culture secretary Tom Watson has called for an urgent statement by the Government: "Camelot has very serious questions to answer about this fraud, which should never have been allowed to take place.
"So too do ministers. Karen Bradley (Culture Secretary) was asked only yesterday in Parliament about security breaches at the National Lottery and she failed to offer assurance that the Government is taking steps to improve it."
A Department for Culture, Media and Sport spokesman said: "It is right that the Gambling Commission has acted in this case and assured us that Camelot has put controls in place to mitigate against any similar licence breach in the future."
