Ottawa police are warning about an aggressive phone scam targeting people of East Indian descent.

A caller claiming to be from the Canada Revenue Agency is threatening arrest, jail time and seizure of bank accounts for unpaid taxes, according to police. The victim is instructed to buy gift cards and provide the information from those cards to the caller.

Even though the calls appear on call display with a 613 area code, police do not believe they are actually originating from Canada.

Victims of this scam are asked to contact police. The organized fraud unit is tracking all complaints.
