The incident drew sharp reactions from university teachers and students as it occurred while they were holding a condolence meeting at the geology and mining department of the second science building at around 11:30am.

According to police investigations, a Jamaat-backed pro-BNP teacher Mia Mohammad Mohiuddin and RU Shibir President Mahbubul Alam Salehi along with three others orchestrated the gruesome murder of Dr Taher on February 1.

Salehi and almost all other Shibir leaders have already left the campus and went into hiding since the declaration of the State of Emergency in the country, said a source.

Most of the participants numbering about 50 who took part in the procession were outsiders and hostel boys while about five unknown Shibir adherents led the rally, said witnesses.

The processionists said they took out the procession to celebrate the inception of 'Bikalpa Sahitya O Sangskritik Sangsad', a cultural platform of Shibir.

The merry-makers were beating drums loudly especially when they were crossing the Second Science building and some of them were dressed as member of Rapid Action Battalion (Rab), bride and bridegroom.

RU Proctor Enamul Haque told reporters that he was not certain whether the procession was legal or illegal during an emergency.

Investigation into the murder case of Prof Taher has been stalled for last nine months due to influence by high police officials, said sources.

The victim's relatives have however drawn the attention of the caretaker government to get justice.
