Detectives last night raided the office of the Bangla daily Inqilab and picked up its news editor Rabiulla Robi.
It could not be known if the raid and the detention followed filing of any case against the daily or the journalist.
But journalists of the newspaper said the police action might be linked to a front-page report on Monday headlined “A police official enjoying unchallenged authority using the prime minister's name”.
They told The Daily Star that a team of some 25 law enforcers stormed the newsroom around 11:00pm and stayed there for an hour.
One of the detectives was carrying a video camera and shooting the activities there. Just before leaving with the news editor, the policemen talked with him about the report, they added.
Contacted, Sub-Inspector Sultan Mahmud of Wari Police Station said he had heard about the incident but no journalist was taken to the station as of filing the report at 2:30am today.
The Inqilab office falls within the jurisdiction of Wari police.
It was the second raid on the newspaper house since January 16. In the previous raid, the office was sealed off following the publication of a report, for which the daily later apologised to readers.
