Just had to tell a dear friend he almost certainly (basically, I'm 100% sure, but can't quite convince him) that he fell victim to a bank fraud.
Phone call by the "police" your account has been compromised, call your bank, they stay on line. Told by "police" to withdraw money, check serial numbers, told they are fake, and give cash to the "courier" we're sending.
Fuckers.
He's on the phone to his real bank now. Fingers crossed for him.
