DENISON, TX-- A Denison woman is being investigated for allegedly stealing more than $70,000 from her employer.

A staff member from the Kelly Oil company told Grayson County deputies Monday that former employee Pamela Joyce Addington allegedly transferred money from the company's bank account to her personal account.

Authorities are looking into bank statements, from as far back as September 2011.

Addington was arrested Tuesday, but has since posted an $80,000 bond.

She's currently on probation for a crime in 2010, where she was charged with theft between $20,000 and $100,000.

Deputies say when the investigation is complete, they will hand the case over to the Grayson County District Attorney's Office.
