Home Minister Asaduzzaman Khan on Thursday said RAB members will soon unearth the mystery behind the murder of journalist couple Sagar-Runi.

‘I don't know about the progress of investigation into the Sagar-Runi murder case but hope RABwill dig out the mystery behind the murders after investigation’, he said while talking to reporters after attending a welfare meeting of Armed Police Battalion, held in the city's Uttara area, reports UNB.

As per the directives of the High Court, the Rapid Action Battalion (RAB) is investigating the Sagar-Runi murder case and they have submitted the progress report on the case before the court, he said.

Maasranga Television News Editor Sagar Sarowar and his wife ATN Bangla senior reporter Meherun Runi were found dead at their rented apartment in the city's West Razabazar area on February 11, 2012.

On April 18, 2012, the High Court (HC) asked the Inspector General of Police (IGP) to hand over charge of probing the journalist couple murder case to RAB.

Replying to a question about the progress of probe into the killing of former police superintendent Babul Akhter's wife Mahmuda Khanam Mitu, the Home boss said, ‘The investigation is going on and the probe report will be submitted within a few days.’

Unidentified miscreants gunned down Mitu at the port city's GEC intersection as she went there to drop her son, Mahir Akhter, 7, for a bus to Chittagong Cantonment Public School and College on June 5, last year.

In a query about the recent killing of a journalist during a clash between two associate bodies of Awami League in Shahjadpur, Asaduzzaman said, ‘Legal action has been taken against those involved in carrying out such attacks, no matter whether he is a public representative or mayor.’
