Online Jamaat-Shibir activists had branded the slain blogger Ahmed Rajib Haider as an atheist who they said should have been resisted.
Rajib, better known by his online identity as Thaba Baba, was one of the main initiators of the movement at Shahbagh, demanding death penalty for war criminals, according to a web post on Sonarbangla, a blog run by Jamaat-Shibir activists.
An image of Rajib's Facebook page was also posted on the same blog.
On February 11, a Sonarbangla blogger with a pseudonym, Sporsher Baire (Out of Touch), wrote about the organisers of the ongoing Shahbagh movement.
Rajib was also named on the site.
After Rajib was brutally murdered in Mirpur in Dhaka on Friday, the Facebook page was not found on the site.
The Daily Star, however, had captured an image of this blog page.
Bangladesh Telecommunication Regulatory Commission blocked the Sonarbangla blog yesterday morning.
The Bloggers and Online Activists Network has been demanding that the government block the page since it launched the protest on February 5 hours after an international crimes tribunal awarded Jamaat leader Abdul Quader Mollah life term for war crimes.
Ahmed Rajib Haider used to write as Thaba Baba on different blogs. In his last Facebook status posted Friday afternoon, he called for banning the institutions owned by the Jamaat-e-Islami, an ally of the BNP-led 18-party opposition, in Bangladesh.
But mysteriously, most of the writings by Thaba Baba are not available on the internet from yesterday. A few of his writings are available, but whether those were written by Thaba Baba is not clear.
According to different bloggers' posts in Facebook, Shibir cadres have continued campaigning against the activists of the movement.
For example, a person named Dhansiri Wahid in his status on Facebook termed several of Shahbagh activists as atheists.
"It is a duty of all Muslims to kill those atheists," he said.
Wahid named Thaba Baba, Asif Mohiuddin, Bami Shial, Arif Jebotik, Doctor Aizu, Nijhum Majumder and other bloggers, saying he wanted to kill them himself.
Another Facebook account holder Farabi Shafiur Rahman in a post said the imam who conducted the namaz-e-janaza of Rajib yesterday at Shahbagh would also be killed.
This person also suggested throwing Rajib's body to tigers at the Mirpur Zoo.
Last month, another blogger Asif Mohiuddin was stabbed at Uttara in the capital by some unknown people but he survived. Asif is a friend of the activists of Shahbagh movement.
