Complaint by Al Rodee :

Good day. I write you to inform you that my mercenary hid an explosive device (lead azide) in the building where your company is located. My recruited person constructed a bomb under my direction. It can be hidden anywhere because of its small size, it can not damage the supporting building structure, but you will get many victims in case of its explosion. My mercenary keeps the territory under the control. If he notices any unnatural behavior or emergency he will power the bomb. I can call off my man if you make a transfer. 20'000 usd is the price for your safety. Pay it to me in Bitcoin and I guarantee that I will call off my mercenary and the device will not detonate. But do not try to cheat- my assurance will become valid only after 3 confirmations in blockchain.
