vrprek.com [194.58.58.155] Bomb threat

Email received Hello.  My recruited person has carried the explosive device (Tetryl) into the building where your company is conducted. It was built  according to my guide. It has small dimensions and it is covered up very well, it is impossible to damage the building structure by this bomb, but in case of its explosion you will get many wounded people. My mercenary keeps the territory under the control. If any strange activity, panic or emergency is noticed he will blow up the device. I can call off my mercenary if you pay. You transfer me 20.000 dollars in Bitcoin and explosive will not explode, but dont try to deceive me -I guarantee you that I will withdraw my recruited person solely after 3 confirmations in blockchain. You have to solve problems with the payment by the end of the working day. If you are late with the payment explosive will detonate.
