Ananta Bijoy Das died instantly after the gang of masked men attacked him with machetes near his house at Subidbazar area in Sylhet city this morning while he was on the way to his office, police said.
"Four armed assailants attacked him when he was going to the town in a rickshaw," Airport Police Station Officer in charge Gausul Hossain said.
Later, Al-Qaeda in the Indian Subcontinent (AQIS) claimed responsibility for Das' murder. The terror group made the claim in a post on justpaste.It. Ansar Al-Islam Bangladesh tweeted a link to the post.
Das, who regularly blogged for Mukto-Mona website, two years ago wrote a poem eulogising self-exiled controversial Bangladeshi writer Taslima Nasreen, who resides in India.
Nasreen herself had shared the poem on her Facebook page, Suprity Dhar, a common friend of Das and Nasreen, said.
Das' family members said he had joined a private bank after completing masters from Shahjalal University of Science and Technology (SUST).
Machete-wielding assailants in February killed 45-year old Roy, a Bangladeshi-born US national, here while his wife narrowly escaped the attack.
Das updated his Facebook status last night, questioning police's role in the killing of Roy and blogger Washiqur Rahman.
His last post, minutes before his murder, was on a ruling party MP's comment that he wanted to whip a SUST teacher.
A month after Roy's killing, another blogger Rahman was murdered in similar fashion in Dhaka but people in the neighbourhood nabbed two suspected killers from the scene and handed them over to police.
Police has so far arrested several activists of little known outfit Ansarullah Bangla Team.
