Mother of slain BCL leader Diaz Irfan Chowdhury went on a hunger strike again on the Chittagong University campus yesterday, demanding immediate arrest of the alleged killers of her son.

Wearing a burial shroud, Jaheda Amin Chowdhury stayed at CU Zero Point for around an hour in the evening, said witnesses.

“The university administration is involved in killing my son. They are patronising the killers,” she alleged.

Earlier on Monday, she started a hunger strike on the campus with the same demand.

The body of Diaz, who was the assistant secretary of the central committee of Bangladesh Chhatra League, was found hanging at his home near Gate No-2 of CU on November 20 last year. His family members were not at home at that time.

The incident is being investigated by the Criminal Investigation Department (CID).
