Hizb ut-Tahrir, a banned militant outfit, is trying to reorganise its organisational activities in the country amid a police crackdown against militancy.
Many activists have started coming out of their hideouts and are trying to carry out militant activities, detective sources said.
Intelligence sources said meritorious students of different colleges and universities are getting involved in the activities of Hizb ut-Tahrir and other militant groups.
Law enforcers are closely monitoring clandestine activities of Hizb ut-Tahrir so that it cannot carry out subversive acts, DMP commissioner Asaduzzaman Miah said.
Hizb ut-Tahrir men persuade students of their coaching centres to become members of the Islamic outfit.
Law enforcers have recently found such type of coaching centres in Uttara, Mohammadpur and Mirpur areas of the capital.
Many innocent students are being encouraged to take part in killing missions and other terrorist activities.
As part of its worldwide programme, Hizb ut-Tahrir leaders and activists brought out processions in different places of the capital and port city of Chittagong on Friday.
During the processions, they also distributed leaflets inscribed with anti-government slogans.
Witnesses said Hizb ut-Tarhir activists came out of different mosques after Jum’a prayers and brought out processions.
They took to the streets right under the nose of law enforcers, witnesses said.
As part of their massive plan, Hizb ut-Tahrir has recently pasted a huge number of posters with anti-government slogans in the capital.
The slogans include establising Islam in the country, saving its sovereignty, its gas and oil, and creating powerful defence forces free from the influence of the United States, the United Kingdom and India.
Police said Hizb ut-Tahrir activists paste posters and distribute leaflets at the dead of night.
The radical Islamist outfit is taking advantages of Rohingya crisis by exploiting popular sympathy to build support for itself.
it has been secretly distributing leaflets in Cox’s Bazar and other parts of the country, highlighting the plight of the refugees, putting up posters and uploading photos of its rallies, all in an effort to gather support for the group.
An intelligence agency said in a recent report that Hizb ut-Tahrir has intensified its activities since the beginning of the Rohingya influx into the country in August.
Acting on the militants’ activeness, the agency ordered its field-level officials to increase vigilance on Hizb ut-Tahrir activities.
The leaflets have blamed Sheikh Hasina for her “late” humanitarian response to allow Rohingyas to enter Bangladesh and criticised her diplomatic role.
The terrorist activities of Hizb ut-Tahrir have come to light after they allegedly attempted to kill college teacher Ripon Chakrabarty in Madaripur about two years ago.
Against the backdrop of its clandestine activities, law enforcers have recently arrested some Hizb ut-Tahrir men from different parts of the country.
Most of the arrestees are students of different colleges and universities, police sources said.
Despite massive operations by police and RAB members, active members of the militant group secretly continued their activities in the country, a RAB official said.
Last month, at least 20 activists was caught red-handed from Muktangan area of the capital.
