An undisclosed amount paid for O'Brien and a friend "to undergo buttock
augmentation procedures at a Las Vegas plastic surgery center," according to the prosecutor's office.
O'Brien had about $30,000 in her possession when she was arrested Wednesday after a traffic stop in Gloucester City, the statement said.
An investigation began late last year after Sea Box officials reported evidence of alleged embezzlement to Cinnaminson police, according to the prosecutor's office.
O'Brien allegedly took the funds over a one-year period ending in December.
She has been terminated by Sea Box, which makes shipping and storage containers, among other products.
The company's website describes SEA BOX as "a multi-million dollar company" with a 134-acre corporate headquarters and manufacturing facility in the East Riverton area of Cinnaminson.
