Nipo Islam Tonne, a former leader of the Bangladesh Chhatra League (BCL) at Dhaka University (DU) and a university official, has been temporarily suspended over allegations of involvement in cocktail explosions and attempts to create instability on the campus.

Tonne is a section officer in the Education-1 section of the university's Registrar's Office.

The university administration has also issued her a show-cause notice, asking her to explain her alleged involvement.

The information was disclosed in a press release signed by Mohammad Rafiqul Islam, Director of the DU Public Relations Office, on Wednesday.

According to the press release, the university took the administrative action after finding preliminary evidence of Tonne's involvement in the cocktail explosions and activities aimed at creating instability on the campus.

Tonne was formerly the president of the Bangladesh Chhatra League's Shamsun Nahar Hall unit at DU.

In the 2019 Dhaka University Central Students' Union (DUCSU) election, she contested on the BCL-backed panel and was elected as a DUCSU member.

She was later appointed as a section officer during the tenure of then DU Vice-Chancellor Professor Md Akhtaruzzaman and was initially posted to the Vice-Chancellor's Office.

She reportedly remained active in Awami League politics even after joining the university as an official.

Earlier, Mohammad Amanullah Aman, a sanitary supervisor at the university's Estate Office, was temporarily suspended over allegations of involvement in the same incidents. He was also served with a show-cause notice.

Pro-Vice-Chancellor (Administration) Professor Dr Mohammed Almujaddade Alfasane told Daily Waadaa that Aman had allegedly offered financial incentives to other university employees to carry out cocktail explosions.

“Those who were approached with such offers reported the matter to us. Following the complaints, we immediately sent members of the proctorial team to the Estate Office,” he said.

He added that Aman Ullah had switched off his phone and fled before members of the proctorial team arrived at his office. The administration has not been able to trace him yet.

Meanwhile, the university administration said a case had been filed with Shahbagh Police Station over the cocktail explosion at the premises of the Faculty of Business Studies on November 10.

The administration said it was taking necessary measures under existing rules against those involved in destructive activities to maintain peace, security and stability on the campus.
