The thefts were discovered in the center's annual review of its accounting.
Ana Limbaring, who has been employed by the Costa Mesa venue for ten years, will be arraigned today on 29 felony counts, including grand theft, falsifying financial records, and computer fraud.
She was arrested and fired earlier this week, and is being held on a bail of $2 million at the Orange County Jail.
Deputy district attorney Randy Pawloski said that Limbaring, who was in charge of accounts receivable and responsible for depositing the center's receipts in the bank, skimmed cash from OCPAC's income, including from concessions. So far, investigators have only uncovered thefts of cash, but are looking into the possibility that Limbaring also used checks or credit-card transactions.
Because Limbaring is a Philippine national, prosecutors are looking into whether or not she could be deported following a conviction.
Todd Bentjen, a spokesman for the center, said "Obviously we are taking this matter incredibly seriously. We will be not only pursing every recovery option, but looking at stricter preventative measures."
