A personal care worker has been accused of stealing $128,500 from an elderly client after a seven-month long fraud investigation.

Police started monitoring a woman employed by Neighbourhood Link Support Services, a Toronto-based non-profit agency, last January.

Fraud investigators allege that the woman made her 87-year-old client sign blank cheques and then made unauthorized payments to herself.

The woman, who was responsible for paying bills on her client's behalf, allegedly paid herself $128,500 between September and November 2010.

Donna Campbell, a 46-year-old woman from Toronto, is charged with 12 counts of fraud over $5,000, criminal breach of trust and possession of the proceeds of crime.
