Prof Abu Dayen, provost of Shahid Rafiq-Jabbar hall, confirmed the matter.
However, the accused Chhatra League activist Hashem Reza, a masters student of public administration department, denied allegation of possessing drugs and termed the incident as a part of political conspiracy against him.
JU administrative sources said the hall authorities along with the security members of the university launched a raid in the dorm around 12:30pm following a secret information and seized some yaba tablets which were kept under the bed of Reza.
The authorities sealed off the room and formed a probe committee for further investigation over the matter. Reza was released after preliminary interrogation.
“A five-member probe committee has been formed to investigate into the matter and it is asked to submit probe report within three working days,” Prof Abu Dayen said.
Following the probe report, the university authorities would take necessary action against the guilty according to the university disciplinary act, Prof Abu Dayen added.
JU unit Chhatra League General Secretary Rajib Ahmed Rasel said: “I have heard the matter. The organisation will take step against Reza if the probe committee finds him guilty.”
