Dhaka--Ananta Bijoy Das was stabbed to death in the street - in daylight, on his way to work in a bank.
A secular blogger has been hacked to death in north-eastern Bangladesh in the country's third such deadly attack since the start of the year.
Ananta Bijoy Das was attacked by masked men with machetes in Sylhet, police say. He is said to have received death threats from Islamist extremists.
Mr Das wrote blogs for Mukto-Mona, a website once moderated by Avijit Roy, himself hacked to death in February.
Sweden has confirmed it turned down a visa request from Mr Das in April.
He had been invited to attend a press freedom event by the Swedish Pen writers organisation but officials in the country's embassy in Dhaka refused the request, citing a risk he might not return home.
Swedish Pen told the BBC they were in the process of submitting an appeal when they heard of Mr Das's murder. The group has demanded an explanation from their government, the BBC's John McManus reports.
Witnesses said four attackers killed Mr Das in broad daylight near his home as he headed to work at a local bank.
Local police officer Mohammad Rahamatullah told Reuters that Mr Das "came out of his house and what we came to know from the local people who are witnesses, was that four miscreants chased him and killed him near his house".
The attackers fled. Mr Das was taken to hospital but declared dead on arrival.
Police say there are similarities in the way all three bloggers were killed - hacked to death with sharp weapons. In each case, attackers carried out their plan on a busy street.
