Subversive activities and anti-government leaflets

This is from roughly two months ago but fits well in the general context of the last few posts:

Law enforcers detained Tasneem Alam, central publicity secretary of Bangladesh Jamaat-e-Islami, at his Uttara residence in the capital yesterday for possession of anti-government leaflets and booklets. 

Police also rounded up 21 female members of Jamaat and its women students' wing Islami Chhatri Sangstha from the latter's office in Moghbazar for their suspected link to “subversive activities.”

 And then a few weeks later, this:

Police detained 13 suspected members of Islami Chhatri Sangstha, women student wing of Jamaat-e-Islami, in front of National Press Club in the capital on Saturday.
Shahbagh police picked them up around 3:30pm while they were coming out of the press club after taking part in a roundtable meeting on women's rights issue there.

(...)

Syed Nurul Islam, deputy police commissioner (Ramna division), said the detainees are suspected to be members of the Islami Chhatri Sangstha and are the aides of the 21 women arrested earlier.
"We are trying to know about their political background and their motives," he said.

As far as I know, being a member of the ICS was not a crime at that point - perhaps this article is actually from the coming April of this year and somehow travelled back in time?
