MINNEAPOLIS (AP) – A Hopkins convenience store clerk is accused using validation codes from lottery scratch tickets to cash in winners before they were sold.

Thirty-four-year-old Mourad Zahi of Hopkins is charged with state lottery fraud, gambling cheating and attempted gambling cheating.

Zahi is accused of “micro-scratching” or revealing a tiny portion of the ticket that contains the validation code that determines if a ticket is a winner.

The investigation began last September when a scratch-off player told the lottery he had a winning ticket for $15 but was told he had already cashed it. Investigators tracked the ticket to a store where a large number of tickets were being manually validated, even though the process has been replaced by barcode scanning.
