They also demanded that all criminals along with their masterminds must be brought to justice.

The call was made from a human chain formed under the banner of 'Blue for Peace' in front of Eden College University in the city.

Speaking on the occasion, President of Nagorik Committee Prof A A M S Arefin Siddique said they are making protest against the 'culture of impunity' that the government indulged in during its regime.

Reza Kibria, son of Shah AMS Kibria, said the government is disinterested in the proper investigation into all political killings.

Asma Kibria, wife of the former finance minister, said 'Blue for Peace' movement will continue until justice is established.

As part of its countrywide consciousness-raising programme against oppression and killing, similar human chain will be formed in Mymensingh town next month.
