Mother of Comilla student Shohagi Jahan Tonu today expressed her disappointment at the slow progress of investigation as no one has been arrested in three months of the killing.

"Will we not get justice because we are poor?" Anwara Begum questioned at a protest rally organised to mark three months of the killing of Tonu.

Comilla unit of Gonojagoron Mancha held the rally at Kandirpar in the city around 11:30am.

Tonu, a Victoria college student and a theatre activist, was found murdered inside Comilla cantonment on March 20, triggering a huge public outcry.
