"A former Giants payroll manager has been arrested and accused by federal prosecutors of embezzling more than $1.5 million from the team over the past year.

Robin O'Connor of American Canyon allegedly took the money from nine unidentified Giants employees between June 2010 and July of this year, according to a recently unsealed affidavit filed in U.S. District Court in San Francisco by FBI Special Agent Jason Richards.

The affidavit said O'Connor, who earned an $80,000 salary, was fired by the Giants on July 6.

"We did discover evidence of possible misconduct by one of our employees which resulted in that employee's dismissal," Giants spokeswoman Shana Daum said Tuesday.

Daum said the Giants immediately notified the U.S. Attorney's Office and the team has been advised not to comment further.

O'Connor, 41, has been charged with two counts, wire fraud and fraud in connection with a computer.

Her attorney was not immediately available for comment late Tuesday.

The alleged embezzlement was uncovered after a recent application O'Connor made to a bank for a loan for a property in San Diego. The application included a letter supporting the application that Richards said was forged.

The letter, purportedly from a Giants human resources manager regarding O'Connor, said in part, "Because of her outstanding contributions to our Major League Baseball team and Front Office during the 2010 season that assisted us in accomplishing our goal of winning the 2010 World Series, she was given two additional payments of compensation in May 2011." The payments referenced totaled about $300,000.

The manager's phone number listed on the letter turned out to be O'Connor's desk number at the Giants' offices in San Francisco, Richards said."
