PHOENIX - Mayra Ramirez, the owner of Dulceria Mayra's Y Mas retail store in Phoenix, was arrested after an undercover food stamp fraud investigation.

According to the Arizona Department of Economic Security, the fraud involving the Supplemental Nutrition Assistance Program totaled more than $600,000.

Search warrants were served Tuesday at two locations.

Ramirez is suspected of using her store to allow customers to exchange SNAP benefits for cash and to purchase items not eligible to be bought with benefits.

"Adhering to the rule of law by aggressively pursuing those who seek to defraud programs designated for those in need is one of the most admirable acts a government can pursue to show its commitment to the protection of taxpayer funds," Department Director Timothy Jeffries said. "We will continue to bring to justice all who commit fraud and steal from those in need. I commend the DES Office of Inspector General for its vigorous pursuit of the individual involved in this massive food stamp fraud operation."

Ramirez was booked into the 4th Avenue Jail Sept. 20 and faces various charges related to the arrest.
