Convicted rapist Edward Putman, has been jailed at St Albans Crown Court for nine years for cashing in a fake National Lottery ticket to claim a £2.5 million jackpot in 2009.
The 54-year-old of Hertfordshire, denied one charge of fraud by false representation.
Putman was found guilty by a jury following a trial at St Albans Crown Court.
A Camelot spokesman said: “We’re aware of today’s verdict and are pleased that this case dating back to 2009 has now come to a conclusion.
“It related to a unique, one-off incident over a decade ago involving a prize claim on a deliberately damaged ticket. It had nothing to do with The National Lottery draws themselves.
“As we acknowledged back in 2016, there were some weaknesses in some of the specific controls relevant to this incident at the time and we’re very sorry for that.
“We’ve strengthened our processes significantly since then and are completely confident that an incident of this nature could not happen today.”
