Huronia West OPP say a local resident has lost $22,000 to the grandparent scam.
Investigators say the woman got a call July 16, from someone posing as an RCMP officer who claimed he had her grandson under arrest and needed $10,000 for his release.
The victim provided the money to a person who came to her house.
The next morning a call came in saying an extra $12,000 would be needed. For a second time a person went to her home and picked up the money.
The OPP remind the public that officers will never contact family members to request money for their loved ones to be released from custody.
If you should receive one of these calls, you should hang up, and contact your local police service to report it.
