The ministry noted that these people have been put on notice and that the investigation into the issue is continuing until officials will get to the bottom of it.
It however stressed that some people are among those arrested who had subversive motives and aimed to cause terror among citizens and students in order to make people pessimistic about the establishment.
The Interior Ministry underlined that officials are trying to find possible links between them and terrorist organizations.
