While cryptocurrency investors take their investments seriously, one man may have taken things too far.  

Last week, a 43-year-old man was sentenced to six and a half years in prison for attempted murder after he sent an explosive device to a UK-based digital currency service provider.  

Jermu Michael Salonen, a Swedish national, sent the device to Cryptopay when the firm failed to reset his account password.  

The Metropolitan Police service said Salonen’s device had the capability to “seriously harm or even kill”.

In March this year, an employee working at the Cryptopay office in Hackney, London, began opening a package believing it to be a regular, everyday delivery. However, the employee grew suspicious upon opening the package and alerted the police.  

The device enclosed in the package was sophisticated in nature and could have caused serious harm. Bomb disposal personnel successfully disarmed the device and counter-terrorism officers launched an investigation.

The Metropolitan Police said the package had been delivered to the address in November 2017 yet had remained unopened for several months.


Investigators from the Met Counter Terrorism Command unit found DNA belonging to Salonen on the package, however, there were no matching records available on British databases. Interpol assisted in the investigation before Swedish authorities caught the culprit.  

Salonen was accused not only of attempting to bomb Cryptopay, but of sending threatening letters to individuals in Sweden and the UK; including the Swedish Prime Minister and a host of government officials in the Scandinavian country.  

Commander Clarke Jarrett, head of the Counter Terrorism Command unit, said: “Salonen seemingly made and sent a device that had the capability to seriously harm and even kill over something as inconsequential as a change of password.” 

The employee that first discovered the device had a lucky escape, according to Jarrett, who added: “Fortunately the bomb did not detonate. It was due to sheer luck that the recipient ripped open the package in the middle, rather than using the envelope flap which would have activated the device.”
