OPP in Huron and Perth Counties are advising you not to open e-mail from people or sources you don't know.
This, after a Seaforth resident recently opened an e-mail containing a threat to her husband.
Police say the communication contained a threat that the woman's husband open a link in the e-mail, or the sender would set off three small explosive devices planted nearby.
Perth OPP located the intended victim, and confirmed he was safe.
Police warn that "bomb threat" scam e-mails are sent to people all over the world, and play on the intended victim's fear so they'll pay the sender.
Investigators say the demands are usually for a large sum of money, and recent variations of the scam often demand payment in crypto-currency like Bitcoin.
