Campus sources said the body took interview of many university officers and employees at the treasurer's room.

Earlier, the Progressive Tea-chers Society (PTS) denounced the probe body saying that there are allegations against the committee members who were appointed controversially during the tenure of BNP-Jamaat alliance government.

Meanwhile, Registrar Prof Abdus Salam has issued letters to all departments, institutions, hall provosts and deans asking them to inform the probe body of any irregularities or corruptions known to them.

But campus sources said many departments and offices did not receive any letter from the registrar as of writing this report.

For this reason, only some pro-BNP-Jamaat officers and employees gave interview in front of the body, they added.

PTS Convener Prof Abdus Sobhan told newsmen that the probe body has not communicated with any of its teacher nor they received any letter from the registrar for interview.

When contacted, Vice-chancellor Prof Altaf Hossain said he will not make any comment on the investigation.

The five-member probe body led by Prof Mahabub Ullah came to RU to investigate the allegations made by pro-Awami League (AL) teachers against RU authorities for controversially recruited more than 500 teachers, officials and employees during the last BNP-Jamaat government.

The pro-AL teachers met the UGC chairman in Dhaka and demanded exemplary punishment to those involved in mass recruitment violating the University Act.
