Earlier, the teachers submitted their leave petitions through respective department chairman.

Campus sources said most classes were not held yesterday, but the examinations were held as usual. The presence of students was also very thin.

Law enforcers were deployed at the entrances of faculties and different buildings on the campus.

Tarek, a student of 2nd semester of management department, said, "We were not aware that our teacher is on leave. We waited for long in our classroom, but the teacher did not turn up."

Meanwhile, pro-BNP and Jamaat teachers took classes in their departments.

"I had to take class on humanitarian grounds following requests from the students," said a pro-BNP teacher.

Some teachers who went on leave expressed their concern over the way the caretaker government is conducting its affairs, saying that it is avoiding its main responsibility of holding a free and fair election.

They also said the government has failed to curb crimes and control the price hike of essentials.

Campus sources said the university authorities have made a list of the teachers who took a day's leave yesterday and asked the department chairmen to provide information about them.

When contacted, RU Vice-Chancellor Prof Altaf Hossain said, "We have made a list of the teachers at the direction of higher authorities."

Several teachers told reporters that intelligence officials have phoned them to inquire about the leave.

Progressive Teachers' Society convener Prof Abdus Sobhan said they would announce their next programme soon to press home their demands.

The demands include lifting the ban on politics, holding general elections at the earliest possible time and freeing educational institutions, including RU, from corruption.
