ACCORDING to news reports some positive developments have been made into the murder investigation of the two foreign nationals. Investigators have claimed to have detected the person who had twitted on behalf of the so-called Islamic State, claiming responsibility for the killing of Italian aid worker Cesare Tavella in downtown Dhaka. Although the detectives are yet to disclose the identity of the sender of the tweet, it is expected that the new evidence will lead to an important breakthrough. 

It is, however, upsetting to witness the reckless, unsubstantiated comments made by political party members regarding the killings, blaming the opponents for masterminding the gruesome incidents. Apart from deflecting focus from the main issue of identifying the criminals, such blame game hampers the course of the investigation. When the issue is used to excoriate the opponents, it only makes light of a very important matter. 

The investigation into the twin murder and its subsequent findings will have positive implications for the country. At stake are Bangladesh's image abroad and also its future as a hub of foreign investment. It is imperative that the probe is conducted with due diligence to clear any misgivings and fear engendered by the murders. We urge all parties involved to refrain from making comments that trivialise such a grave issue or potentially harm the investigation and influence its outcome.
