Bomb threat email, subj: "I advise you not to call the police"
Partial email message body: "Good day. There is a bomb (tronitrotoluene) in the building where your company is conducted. My recruited person constructed the explosive device according to my instructions. It can be hidden anywhere because of its small size, it is impossible to destroy the structure of the building by my explosive device, but in case of its explosion you will get many victims.
My man keeps the territory under the control. If any unnatural behavior, panic or emergency is noticed the device will be blown up.
I can call off my recruited person if you make a transfer. 20'000 usd is the price for your safety. Tansfer it to me in Bitcoin and I ensure that I will withdraw my mercenary and the bomb won't explode. But do not try to deceive me- my warranty will become valid only after 3 confirms in blockchain network.
