Provincial Police in Sioux Lookout say someone has been calling local residents, posing as a lawyer, advising that one of their family members had been arrested in Quebec, and money was needed to get them released from jail.
The caller then proceeded to give instructions on how to transfer the money using a Western Union money transfer.
OPP say the residents realized it was a scam after they had sent several thousands of dollars to the suspect.
It's not known how many people fell victim to the scam.
Police are investigating but warn that you should always ask relevant questions and verify all information before sending any money.
