Risking lives, some students were seen riding on the train roof due to lack of seats in the train’s bogies.

As the train arrived in Fatehabad area under Hathazari upazila, some students fell off the train after being hit by a branch of the tree which was hanging low due to rains.

Moazzem Hossain, a first year student of the university’s Public Administration, told UNB that three students fell off the train’s roof after being hit by the branch of the tree when the train was crossing Chowdhuryhat area around 9pm.

Moreover, some 15 to 20 were injured in the incident and eight students were in critical condition, he said, narrating the incident that most of the students sustained injuries in their heads and faces.

Enraged by the incident, the CU students vandalised the campus's police outpost, shops, their valuables including chairs and tables and set fire on tyres in front of the Zero Point of the university.

At one stage, they also moved to the bungalow of the university’s VC and also went on rampage there, creating panic on the campus.

Ratan Kumar Chowdhury, manager of Chattogram Railway Station, said that students are always asked not to ride on the train’s roof due to lack of safety but they are indifferent to the instruction.

After the accident, the train carrying the students reached the campus, he said.

Dr Md Morshedul Alam, assistant proctor of the CU, said some 15 to 20 students were critically injured as they fell off the train roof after being hit by the tree’s branch.

Two shuttle trains carrying students between the campus and the New Market Station daily.

Moreover, movement of demu trains was suspended due to lack of manpower after the Covid-19 pandemic.

The number of trains and their bogies did not increase to meet the growing number of students every year.

Currently around 28, 000 students study in the university.
