A 37-year-old St. Catharines woman has been arrested, facing accusations that she bilked her employer out of more than $554,000.

Niagara Regional Police say detectives issued a warrant for the woman's arrest, after an investigation into complaints by a Ridgeway dentist alleging his general manager had been defrauding his office for three years, from December 2014 to November 2017.

The woman was arrested Wednesday while crossing the Rainbow Bridge into Canada.

Charged with fraud over $5,000 and laundering proceeds of crime is Jennifer Leslie.
