The Counter Terrorism and Transnational Crime (CTTC) unit has sought help from the citizens of the country to trace four militants involved in killing of bloggers.
Through a Facebook post on Monday, the CTTC has published images of the four militants and urged people to inform the organisation of their whereabouts through message, call, or using the Hello CT app.
The identities of the informants will be kept confidential.
Saiful Islam, deputy commissioner of the CTTC said that the four wanted militants were members of the banned militant outfit Ansar-al-Islam (ABT), and police came to know about them based on the interrogation of the militants who were already in the custody.
The militant group started target killing since 2015. So far, they have killed blogger Razib Haider alias Shovon, Ovijit Roy and Niloy.
