Dhaka: Bangladeshi authorities should immediately release Probir Sikdar, an editor who was arrested on Sunday, said the Committee to Protect Journalists (CPJ).

‘Jailing journalists for publishing threats made against them further undermines confidence in Bangladesh’s legal system,’ said CPJ Asia Program Research Associate Sumit Galhotra.

Galhotra called on authorities to immediately release journalist Probir Sikdar and investigate the threats against him.

Detectives arrested Probir Sikdar, editor of the online news portal Uttoradhikar 71 News, at his Dhaka office, it said quoting news reports.

Sikdar was arrested following a complaint that alleged he had ‘tarnished the image’ of a cabinet member belonging to the ruling Awami League party, said the CPJ.

In a Facebook post earlier this month, Sikdar said he had been threatened and that three individuals, including Khandaker Mosharraf Hossain, Minister of Local Government, Rural Development and Co-operatives, as well as a convicted war criminal and a businessman, should be held responsible if something happened to him, according to police cited in the independent newspaper The Daily Star. The nature of the threats is unclear.

The threats followed stories Sikdar published last month about the war criminal and the businessman, according to The Dhaka Tribune.

The journalist posted the story to his Facebook page. The journalist said when he went to a local police station to document the threats, the police refused to log one, according to news reports.

The official complaint against Sikdar was filed under section 57 of the Information and Communication Technology (ICT) Act, which regulates Internet use in the country.

Section 57, which has often been used against journalists, criminalizes any information published on websites that ‘encourages dishonesty, offends anyone, or tarnishes the image of the state or any person,’ according to news accounts.

Sikdar has worked as an investigative journalist for several Bangla-language dailies over the years, according to news accounts.  In 2001, he was physically attacked after he reported on events surrounding the anniversary of the 1971 war of independence.

Following a February visit to the country, CPJ noted journalists have been under heightened pressure from authorities when reporting critically on authorities.
