A few times I got the following call:
Caller claims they are the rcmp. They have seized a rental car that was used to transport drugs from Canada to San Antonio. The US police found the car abandoned in San Antonio, and traced it to me. Allegedly because the car was a rental, and it was my credit card used to rent the car.
Caller says it's probably not me who rented the car, but it doesn't matter because it's my credit card used to rent it, so as far as the police is concerned, they are looking for me. Caller says he has an arrest warrant with my name on it, and unless I take care of it, I will get arrested at the next opportunity. And to take care of it... you guessed it!... he needs my bank information.
So I asked him whose name is on the arrest warrant. He couldn't answer obviously, just kept repeating that he has an arrest warrant. And I kept asking him whose name is on it. Eventually he hung up.
