Police have charged a 56-year-old Windsor woman after an investigation into fraud allegations at a local manufacturing company.

Nada Khalaf, 56, is facing charges of fraud over $5,000 and uttering forged documents in the case. She had been working as a bookkeeper for a Windsor manufacturing company.

Const. Andrew Drouillard of the Windsor Police Financial Crimes Unit says officers are still poring over documents from an undisclosed Windsor business, "There are potentially two instances of this now, so we want to make the public aware."

Windsor police were called in to investigate in February, when the company learned that their former bookkeeper had previously been charged by the OPP with fraud-related offences in connection with a manufacturing company in Leamington.

At that point the Windsor complainant began to review financial documents from the time the woman worked for his company between 2008 and 2012.

As a result, he alleges she defrauded the company of more than $400,000 through fraudulent payroll deposits, petty cash expenditures and forged cheques.

Drouillard says that's when the owner went to police, "The complaint stated he found there were fraudulent payroll deposits, petty cash expenditures and fraudulent cheques that were written."

Following an investigation by the Windsor Police Financial Crimes Unit, the female was subsequently arrested and charged.

The investigation is still ongoing and police say the financial losses are likely to increase.

Anyone with information is asked to contact police at 519-255-6700 ext. 4330 or Crime Stoppers at 519-258-8477.
