The real victor, who police did not name, purchased the $30 scratcher lottery ticket at the Lucky Grocery Store in the San Francisco Bay area on December 20. The ticket turned out to be worth $10 million.
He told his two roommates about the win and tried to claim his prize the next morning.
"One of his roommates goes to the same store, purchases the same ticket", said Chris Polen with the Vacaville Police Department.
Lottery officials want to make sure that the true owner of the ticket will still be able to collect his $10 million.
Investigators say the man went to collect his winnings the next day and was told he was not a victor.
Authorities announced on Tuesday that the recent investigation into a stolen scratcher lottery ticket led to an arrest and the discovery that the recovered ticket was actually worth $10 million.
According to the station, lottery officials were unaware at that point that the ticket had been reported stolen but began the routine investigation that they conduct on all winnings over $600.

Deputy Prime Minister Luigi Di Maio, who heads the anti-establishment Five Star Movement (M5S), wrote on his party's blog. He abandoned the tax hike and announced last month a series of measures to boost purchasing power.
A day later, Saosongyang arrived at the lottery office with the real ticket.
Saosongyang went to collect his winnings on Monday in Sacramento but was instead greeted by Vacaville police officers.
The man who actually bought the ticket will be awarded his winnings after lottery investigators verify his identity, according to the statement. Lottery officials then invited Saosongyang to its office under the premise of awarding the prize. Investigators visited the store and found out that the ticket had been stolen.
"This is when the lottery investigator and a Vacaville PD Detective began comparing notes and working together on this theft investigation", the Facebook post read.
He did so, and was promptly arrested for grand theft and taken to Sacramento County Jail, bringing to an end one of the least well-executed criminal heists in recent memory. They determined the roommate had purchased a similar Scratcher Lottery Ticket, altered it, and swapped it with the winning ticket.
He remains jailed and it's unclear if he has an attorney.
