A pro-Roma organisation in Prague was threatened to be firebombed. According to Czech police this is not a criminal act
19. 1. 2017
In December 2016 the Prague Pro-Roma organisation "Romea" made an official complaint to the Czech police that a person on Facebook threatened to firebomb their offices. The Czech Police has now informed Romea that the firebombing threat "is not a criminal offence" and it has therefore shelved any further investigation of the matter.
